			  INTRODUCTION

     Winh19, Winh19k, and Winker are communications programs
running under Microsoft Windows and emulating the Heath/Zenith
H/Z-19 terminal.  The programs provide both Heath and ANSI modes. 
Consequently, the main features of  the Heath/Zenith series
terminals are available in the Windowing environment.

     The emulation features a very precise rendering of the
H/Z-19 keypad as well as a font containing the original graphics
characters.  Certain improvements have also been made over the
original design.  In particular, some function keys can be
programmed, default settings can be made from the program, and
the number of lines and columns the terminal has can be preset in
win.ini.

     Winh19 contains only the terminal emulator.  At run time, it
uses the least memory of the three programs.  Winh19K and WinKer,
which are functionally equivalent, additionally contain the
Kermit file transfer protocol.  Having most of the basic features
of any Kermit implementation, the user can transfer files and
control the host whenever the latter is also capable of running
Kermit.  The programs are distributed as the pair Winh19/Winh19k
or as WinKer alone.

     Since these are  Windows programs, the user can have up to
two transactions in progress simultaneously, and file transfers
can take place while other programs are active.

        Only a few features of the H19 are not available.  Later
we discuss the precise differences, but briefly they are: no key
click control, no Enter key emulation on the keypad, and the
special keys on the top row have been relabeled.

     The current version also lacks a few standard features of
Windows.  There is no selective copy-to-clipboard function. 
However the entire contents of the video buffer can be slapped to
the clipboard, and text can be pasted into the program.  In
addition some keys do not have a corresponding menu item.


     UNIX users can specify h19 in their TERM variable to obtain
Heath mode.  If this is not available, vt52 may suffice. 
Alternatively, one can specify h29, h19a, or  ansi.  Depending on
how well the termcap file has been written, such features as
cursor key operation may or may not be recognized.

       The programs will run only in Windows 2.03, Windows/286,
or Windows/386.  Windows 1.x is already obsolete.  If you are a
registered owner of Windows, you can receive an upgrade from
Microsoft at a nominal price.

     To appreciate fully the features of this terminal, the user
should refer to the original Heathkit documentation.  We have
summarized most of the commands in the Appendix, but the
information is abbreviated.  The best source of detailed
information is in "Heathkit Manual for the Video Terminal, Model
H19, Operation", Part Number 595-2284-01, Heath Company, Benton
Harbor, MI 49022.  
 

		       TERMINAL OPERATION

     The programs are very easy to use.  Simply copy the one you
wish to your Windows directory and run it from Windows.  You will
be asked if the default entries should be added to win.ini.  If
you agree, win.ini will be modified and you can then continue.
Otherwise the program will exit.  If you agree to continue, the
program will try to open the first communications port specified
in win.ini.  If this is not successful, it will try the next one
listed.  If this one also fails, the program will exit with a
message.  We assume only COM1: or COM2: are available.

     If a port is opened and successfully initialized, you will
find yourself already on-line and ready to communicate.  Most
communications and terminal parameters may be changed during the
session using the Set Communications and Set Terminal options in
the Emulator menu.  The values you choose can be saved
permanently by checking the 'Save' item in the dialog box.  In
addition, by checking the 'Default' item in the communications
dialog box, the selected port becomes the first port tried when
the program is run.

     With the Edit menu you can paste text from the clipboard
when on line, and you can copy the contents of the entire screen
to the clipboard.  No attempt has been made to preserve such
attributes as inverse video or the graphics characters during
copy.
    
    If you plan to use the graphics character set of the H19
terminal, you should install the font Winh19.fon with the Windows
control panel.  Otherwise, you will get the normal Windows
terminal (OEM) font, and if you go into the terminal's graphics
mode, you will see the usual characters supplied by IBM for the
control characters.  You may want to install the extra font at
any rate if you are using a display such as the EGA where the OEM
font is really too small, or the AT&T/Olivetti 640x400 screen
where the OEM font is a bit too large to get the entire H19
window on the screen. Winh19.fon is in the Windows 2.0 format.



			 Basic Functions

     It is typical of terminals of this type that every operation
is performed by its receiving commands as sequences of characters
prefixed by the escape character.  Such sequences can originate
from the keyboard if the terminal is off-line or can be received
from the host.  Only one setting cannot be changed in this way,
and that is whether the terminal is to run in local-echo mode or
not.  All other operations are obtained via escape sequences.
Typically, however, a user needs to know very few of these
commands; the host computer, if it knows the terminal type, will
perform them as required.  However, most basic operations can be
carried out using the keyboard and/or the menu.

     The Off Line/On Line menu item can be used to toggle between
line and local modes.  Either click on the item with the mouse or
simply type ALT-O (Letter O).  In local mode you can explore the
entire range of the terminal's capabilities including the
behavior of the keypad, which has been organized exactly as the
keypad on the H19.  In particular you can make mode and setting
changes by typing the corresponding escape sequence.  For
example, to set the terminal to 300 baud when in Heath mode, go
off-line and type ESC r C.  To set a block cursor,use the
sequence ESC x 4.  See the Appendix for a complete list of such
commands.

     Function keys F1 to F5 and F7 to F9 can be programmed to
send user-defined strings if the control, shift, or control-shift
keys are also actuated.  Function key F10, and if you have an
extended keyboard, F11 and F12, can additionally be programmed in
unshifted mode as well.  F6, which plays the role of the ERASE
key on the H19 cannot be altered.  The ability to program the
function keys is NOT part of the standard capabilities of the H19
but is an added feature.  See the win.ini discussion below for
more information on setting these keys.

     Some terminal commands are available directly from the
keypad or the function keys.  For example, F6 will clear the
screen from the present cursor position to the end of the screen,
and Shift F6 will clear the entire screen.  If the terminal has
shifted keypad mode set, then the keypad performs editing
functions.  In particular, cursor movement is as expected. 
However, the rest of the keypad may function differently from the
actions marked on the keys as its action in this program is
exactly as on a real H19.  A complete account of keyboard usage
is in the Appendix.


     Note that all of the editing key actions such as clear
screen, delete a line, move cursor, etc., will not be transmitted
to a host when on-line if the control key is held down.

     You can send a break with CTRL-BREAK, or on an extended
keyboard, CTRL-SCROLLOCK.  The break signal is active as long as
the key remains depressed.  CTRL-BACKSPACE will send a DELETE
character to the host.  CTRL-J will send a line feed character. 
The emulator can be reset to its 'power-up' values by using the
Reset selection in the Emulator menu.

     Finally, you can use the Scroll Lock key to conveniently
stop and start the display.  Hold screen is also available.
Simply go off line and type the appropriate escape sequence for
the emulation mode in use.  Then when a carriage return is
received on the bottom line, the display will pause until you
strike the Scroll Lock.  This will allow the next line to
display.  You can see the entire screen by holding down the shift
key when depressing Scroll Lock.  To end the hold screen mode,
again go off line and type the correct sequence. 
 
Win.ini Settings

     Here is a typical set of values in win.ini along with some comments.

       [Winh19]
	port1=COM2:		; try to open this port first.
	port2=COM1:		; if unsuccessful, try this one next.
	COM1:=1200,e,7,1	; set this port to 1200 baud
				;    even parity, 7 bit word, and 1 stop bit.
	COM2:=9600,n,8,1	; set this one at 9600 baud, no parity,
				;    8 bit word, and 1 stop bit.
	BlockCursor=0		; set to 1 for a block, 0 for an underline cursor.
	Keyclick=1		; currently not implemented.
	WrapAround=1		; terminal does line wrap if set to 1
	AutoLFonCR=0		; does LF on receipt of CR if set to 1
	AutoCRonLF=0		; does CR on receipt of LF if set to 1
	ANSIMode=0		; Heath mode if 0, ANSI mode if 1
	ShiftedKeypad=1	; Keypad is shifted if set to 1 (keypad sends
				;    edit function commands).
	FullDuplex=1		; Terminal is in local echo if 0.
	lines=24		; 24 lines plus status.  Maximum is 40
	columns=80		; 80 columns.  Maximum is 95
	SF1=ATDT 5555555	; Shift F1 sends this Hayes-like dialing sequence.
	SF2=whall		; Shift F2 sends my login command.
	CF1=ats16=5d		; Control F1 turns on analog loopback on a
				;     U. S. Robotics Courier modem.
	CSF2=atz		; Control Shift F2 resets U. S. Robotics Courier modem.
	CSF3=dir\M		; Command to display a directory on host.

     The settings for COM1 and COM2 are in the format for an
MS-DOS mode command.  In particular, you cannot currently select
either a default parity of mark or space.  However, you can
configure the terminal for such a parity type from within the
program.

     The number of lines or columns can only be set by editing
win.ini. You may want to experiment with suitable values.  On an
EGA display, 27 lines works well.  30 lines gives a nice display
on the AT&T/Olivetti 640x400 monitor.  Finally, you can use up to
36 lines comfortably on the VGA.  95 is the upper limit for the
number of columns.  Don't forget to inform the host computer
about the number of lines on your terminal if you select
non-standard values. 

     The keystrings and corresponding keys are as follows:

		F10 to F12		F10 to F12
		SF1 to SF12		Shift F1 to Shift F12
		CF1 to CF12		Control F1 to Control F12
		CSF1 to CSF12		Control-shift F1 to Control-shift F12

You can change these strings from the program with the Edit
Function Keys menu.  Note that when editing, you have complete
capability to cut, copy, and paste the strings from one selection
to the next.  However, you must use the keyboard interface at
present, although the mouse can be used to select text for a copy
or cut operation, as well as to save the string to win.ini.

     Control characters ^@ (NUL) thru ^[ (ESC) can be used in
strings by prefixing with a backslash '\'.  Thus '\M' means a
carriage return and '\[' is an escape.  To place a backslash in a
string use '\\'.

     Note that key F6 is currently always grayed and cannot be
selected in the dialog box.

Winh19.fon

     WINH19.FON is an OEM type font using a Modern typeface. 
Characters are 7x9 with extenders in an 8x10 cell.  Characters 32
to 126 are standard ASCII but are not faithful reproductions of
the original H19 forms because they were found to be too light on
a Windows screen to be easily readable.  However, characters 0 to
31 and 127, the  graphics characters, are exactly the same as the
original in shape and composition.  In order to see the graphics
characters, the user must first set the terminal to graphics
mode.  Then the lower case letter keys plus some of the
non-alphabetic keys will display the graphics set.  See the Heath
manual for complete information including bitmaps of each
character. 
 
Differences with an actual H19

     The following differences exist between our emulation and
the real machine:

    1.  Key click cannot be turned on or off.  This is simply
regarded as too hardware-dependent to implement.

    2.  An extension has been made to the H19 Scroll key.  When
in hold screen mode, the Scroll Lock key functions just as on the
H19.  However, in normal mode, Scroll Lock can also be used to
stop and start the display if you have XON-XOFF enabled on the
host.  The Scroll Lock key prevents any further reading of the
communications port when toggled on.  The effect is that the
Windows communications driver sends XOFF to the host, effectively
stopping the display.

    3.  Since many IBM-style, 83-key keyboards lack a keypad
Enter key, the corresponding H19 functionality is also absent.
Unfortunately, even on an extended (101/102-key) keyboard, it is
impossible to determine in Windows whether the keypad or main
ENTER key has been depressed.

	4.  On an extended keyboard, the Break key does not send
a key released signal.  So Windows simply returns both a keydown
and keyup message when the key has been depressed.  So you must
use Control Scrollock to set and reset the communications break
state on an extended keyboard. 

	5.  Keyboard correspondence with the 83-key keyboard is
as follows:

		HEATH H-19			WinH19
		
	Main keyboard:
		Off Line			ALT-O (menu)
		f1				F1
		f2				F2
		f3				F3
		f4				F4
		f5				F5
		Erase				F6
		Shift Erase			Shift F6
		BLUE				F7
		RED				F8
		WHITE (GRAY)			F9
		Reset				ALT-E-R (menu)
		Break				Control Break (see note 4 above)
		Scroll				Scroll Lock (see note 2 above)
		Line Feed			Control J
		Delete				Control Backspace

	Keypad:	
		Insert Character (7)		Home (7)
		Up (8)				Up (8)
		Delete Character (9)		PgUp (9)
		Left (4)				Left (4)
		Home (5)			(5)
		Right (6)			Right (6)
		Insert Line (1)			End (1)
		Down (2)			Down (2)
		Delete Line (3)			PgDn (3)
		Zero (0)				Ins (0)
		Decimal (.)			Del (.)
		Enter				None

All other keys are the same.  For more information, see the Appendix.


			KERMIT OPERATION


     Winh19k and Winker contain an implementation of the Kermit
protocol developed by the Center for Computing Activities at
Columbia University.  The following information will help you use
Kermit.

     The Kermit protocol provides a way to effect an error-free
file transfer files between two, possibly very different
computers provided each is capable of running Kermit.  Kermit
also has several other features which allow one machine to act as
a server while the other computer controls the server's actions
by means of remote commands.

     If you are a regular user of Windows, then there are several
advantages to using a version of Kermit directly from Windows.
First, since Windows is multi-tasking, you can run simultaneous
transfers from up to two communications ports (but, see the notes
below) and continue to use other applications.  Secondly,
transfers continue even when the window is iconic.  Finally,
programs written for Windows can be controlled by its memory
management system for optimum memory usage.

     Windows Kermit currently can send and receive files and has
a fairly complete set of commands for interacting with a remote
server.  The program cannot act as a server (yet), and, at this
time, only a few file-transfer parameters can be set.  In
addition, file compression is not yet implemented, and only the
standard 1-byte checksum is available.  The eight-bit quoting
mechanism is in place so that binary file transfer over 7-bit
connections is possible.  But, there is no turn-around character
mechanism, so certain IBM mainframe Kermits may not work with
this implementation.

     File transfers frequently fail because of incompatible
parity and word size settings between the host and the local
Kermit.  You will usually get your best results by using eight
bits and no parity.  Any other settings will cause binary file
transfers to be slower since the eight-bit quoting mechanism will
go into action.

     There are currently no DOS services allowing you to change
directory, display a directory, type a file, etc.  However, you
can easily use the MSDOS.EXE window to show the files in a given
directory.  And, you can take advantage of some features in the
SEND dialog box to help you move to another directory and to list
the files there.  After you are done, just push the CANCEL
button.  For information on using SEND, see below.


Basic Usage

     Kermit is very easy to use.  To send a file from the local
computer (usually the controlling microcomputer) to the remote
(host) machine the steps are:

	1.  Run Kermit on the remote.  At the prompt type
'receive'

	2.  Choose the 'send' option on the local machine, select
the files, and confirm the selection.  The transfer will begin
and continue until all files selected have arrived at the host or
the transfer is canceled.

     To receive a file:

	1.  Run Kermit on the remote machine and select 'send'
along with the target file names.

	2.  Select 'receive' on the local machine.  The files
will continue to arrive until the transfer is complete or  is
canceled.

     To use remote operations:

	1.  Run Kermit on the remote machine and select 'server'.

	2.  Issue all commands from the local machine.  Typical
commands are send files, get files, get help, type or delete a
file on the host, etc..

	3.  Terminate remote operations by issuing the 'finish',
'bye', or 'logout' command. 

     During a transaction, the terminal display window is removed
from the screen and various items reflecting the state of the
Kermit process are shown.  If a file is being transferred,
statistics about the transfer are displayed.  If a remote command
is being executed, any information is written to the bottom line
of the window and is scrolled upward.  At the end of the
transaction, a dialog box appears announcing success or failure. 
The display may be obscured by the box, but it can always be
moved out of the way.  However, once 'OK' has been pressed, the
terminal display window is restored and the old information is
lost.

     Once a file transfer has begun, you can minimize the window
and have the transfer continue 'in the background'.  The icon
will display the packet types and numbers for both the outbound
and inbound packets. 

Warnings

     File transfers usually fail because of differences between
the local and remote parity and word size.  If you cannot get
even the first packet across, then try changing these parameters.

     Windows is multitasking and you can run several instances of
the same program.  If you are running two copies, watch out for
possible file conflicts such as trying to transfer files to the
SAME file from two different remote Kermits.  The DOS file system
does not always protect you from this kind of error. It can
happen that while you are receiving a file from one source, the
same file can be successfully opened for sending. It usually
means disaster for the incoming file.

     Similarly, if the target file is a floppy disk, do not
remove the disk until the transfer has completed. 

Detailed Information about the Commands

     Three menu selections control the operation of the Kermit
protocol.  They are: Protocol, Files, and Remote.  Files handles
send, receive, get, and the various means for canceling the
transfer.  Remote contains all commands which can be issued to a
remote server.  Finally, Protocol allows a limited selection of
options.

     All menus are provided with accelerators as indicated by the
underlined character.  Please see your Windows reference manual
for instructions on using accelerator keystrokes.  We have listed
below when applicable the accelerator keystroke sequence for each
command. 
 
The Protocol Menu

     Currently you may select the following items:

	Timeout on:  If this item is checked, then after a
certain number of seconds have elapsed with no packets received,
a retry will be attempted.  If the number of retries exceed a
given threshold, then the protocol will exit.  Currently the
elapsed time is fixed at 5 seconds and the number of retries is
also 5.  Neither can be varied in the current implementation.

	Duplicate filename warning:  If checked, then an incoming
file with the same name as an existing one will be renamed so as
not to overwrite the old one.  The new name appends or replaces
part of the old name with a unique generation number.

	Discard incomplete file:  If checked, then any file being
received in which the protocol has been interrupted by an error
condition or by the user will be deleted.

	Bell at end of transfer:  If checked, the bell will sound
when a transaction is complete or canceled.

     If the 'Save settings' box is also checked, then win.ini
will be modified to reflect the new defaults under [Kermit]. 

The Files Menu

     Using these selections, you can send or receive a file or a
group of files.  Before a transaction begins, you can select
either of Send, Receive, or Get.  After the transfer has begun,
you may interrupt the transfer in various ways.  Of course, you
should have already set the remote Kermit as described above. 
Thus, before you attempt to receive files you should have already
set the remote Kermit to send them.  Similarly, if you are
sending files to the remote Kermit, you must first command it to
receive or place it into server mode.  Finally, server mode on
the remote host must be active in order to use the Get command.


	Send (ALT-F-S):  When Send is selected, a dialog box with
several windows appears.  Two are list boxes; the one on the left
contains all files matching the search specification shown in the
edit box at the top.  The right list box contains a list of paths
and disk drives which can be accessed.  The push buttons allow
you to select a list of files based on the search specification,
send the selected files, or cancel the operation.

     The basic principle is that a file name must be highlighted
in the list box to be sent.  Thus, you may send several files.
However, you may select only those files from the current
directory.  Hence files from more than one directory cannot be
sent during one transaction.

     A file can be selected in several ways.  The usual method is
to click on the name with the mouse.  More than one file can be
highlighted by holding down the shift key during selection.  You
can also deselect one of several highlighted items in the list by
again depressing the shift-key and clicking on the item.  If you
do not hold down the shift key, all items will be deselected
except the one to which the mouse is pointing.

     You can also use the keyboard to select files.  Use the tab
key to move to the files list box.  There you can select files by
using the arrow keys to move through the list and the shift key
to highlight contiguous items in the list.

     The default search specification is "*.*".  You can choose
another string to limit the files displayed in the list box.  For
example, if you tab to the edit box (or point to it with the
mouse), type "*.txt", and press the RETURN key or the SELECT
pushbutton, then not only will all files having that extension be
displayed, but all will be selected as well.  You can then send
the entire list by activating the SEND button.

     At any time, you can deselect all files but one in the list
box by simply pointing and clicking on that file.  You can
deselect all file in the box by deleting the contents of the edit
box and pressing RETURN.

     You can move to another drive or directory by typing it into
the edit box and pressing RETURN or double-clicking on the
corresponding item in the right list box.  The current search
specification is appended to the path, the program moves to the
new directory, and all matching files are displayed.  A second
RETURN or a push of the SELECT button then highlights the files
list. 

     Finally, at any time, a single file located anywhere in the
system can be selected and sent.  Simply type its name, along
with any required drive and/or path information and hit RETURN.
If the file can be found, then a switch is made to that directory
and the file name is displayed and selected.  If the file cannot
be found,  no action takes place.

     You may cancel the operation at any time by pressing the
CANCEL button.  Pushing SEND with no files highlighted has the
same effect.

	Receive (ALT-F-R):  If the Receive menu item is chosen,
then the program enters a state where it is awaiting the arrival
of an initialization packet from the sender.

	Get (ALT-F-G):  If the remote host is in server mode, you
may use this command to receive files.  A dialog box appears in
which you can type a single file name or a search specification. 
After the OK button has been pressed, the program sends a
initialization packet and then waits for the file(s).

	Exclude file (ALT-F-X):  Once a transaction has begun,
you can exclude the file currently being transferred by selecting
this menu item.  The rest of the files will not be affected. Note
that if you have elected to keep partial files, the current file
will NOT be deleted if you are receiving.

	Zap batch (ALT-F-Z):  Once the transaction has begun, you
can kill the remaining transaction by making this selection. 
Only the current and remaining files in the list are affected.
The comment about partial files in the paragraph above also
applies.

	Error abort (ALT-F-E):  When this item is selected, an
error packet is sent to the remote Kermit and the transaction is
terminated.  Incomplete files are discarded (or saved, if the
partial file flag is set).  Use this method to cleanly terminate
a transaction once the exchange has started.

	Cancel protocol (ALT-F-C):  This selection is most useful
as a way to cancel a transaction before any exchange of packets
has begun.  Note that the remote Kermit will attempt to continue
if it has already started and you will may have to use other
means to terminate the remote program, or, you can simply let it
time out. 
 
The Remote Menu

     You may control many actions of the remote host by placing
its Kermit into server mode and then using the various commands
available under this menu item.  Many of the commands will
present you with a dialog box, although in some cases, the
information is optional.  In any case, you confirm your selection
by pushing the OK button.  A touch of the space bar is
sufficient.  Press the CANCEL button and the transaction will not
start.  

     Some remote commands may return many lines of information.
You can stop the display (for a limited time, as the remote
Kermit may time out) and restart it by toggling the Scroll Lock
key.  Finally, during the transaction, you can use the various
cancel options to abort the operation.

	Help (ALT-R-H):  This item will request the host to
display the remote commands available.  Some remote Kermits may
be able to respond to help about a particular subject, and a
dialog box is available to add the additional string.

	Host Command (ALT-R-O):  Use this item to have the host
perform a shell command.  An entry in the dialog box is
mandatory.

	Finish (ALT-R-F):  Select this item to cause the remote
Kermit to exit the server mode.

	Logout (ALT-R-L):  As the name implies, this item is used
to log off the remote machine from server mode.

	Bye (ALT-R-B):  This selection logs off the user from the
remote and exits the local Kermit.

	Chdir (ALT-R-C):  You can change directory on the remote
server with this command.  A dialog box will appear allowing you
to enter the new directory, and, if needed, password.  The
password will not be displayed.  On some remote Kermits, if you
make no entries, the current directory is returned.

	Directory (ALT-R-D):  This item lists the files located
on the remote host.  An optional search specification can be
given. 

	Type (ALT-R-T);  You can type a file or group of files
located on the remote host with this command.

	Delete (ALT-R-D):  This menu item allows you to delete
files on the remote host.

	Who (ALT-R-W):  You can list the users on the system with
this command.  An optional string can also be sent.

	Space (ALT-R-U):  This command lists the disk space
available on the host.  An optional string can be sent.

SUMMARY OF WINDOWS MAIN KEYBOARD USAGE FOR THE WINDOWS H19 EMULATOR

Note:  Keyboards covered include IBM-style 83 and 101-key (extended) 
models.  F10, F11, F12 are available only on 101 key keyboards. 
Other differences are noted below.

(1) Heath mode replies with ESC Y a b, where a and b are characters
whose ASCII values are, respectively, the row and column position of the
cursor plus 31.  ANSI mode replies with ESC [ r;c R where r and c are
character strings of digits for the row and column position of the cursor. 

(2) In the Heath mode, a and b are ASCII characters whose values are the
respective row and column postions offset by 31 (if the first row or
column is regarded as 1).  In ANSI mode, r and c are character strings
of digits for the row and column position.
