Honeywell GCOS Kermit
.br
Version 1.1
.br
January 1985
.sp
.pg
This writeup describes the features and use of Kermit-GCOS, a program for
Kermit protocol file transfers. Kermit-GCOS runs under the Honeywell
GCOS time sharing system (TSS) and should normally be installed
on the TSS command library as file CMDLIB/KERM
to run as the TSS command KERMIT.
It can, however, be placed on any user catalog and run
as a TSS user program.
Kermit-GCOS was written by John Huxtable, University of Kansas
Academic Computing Services.
.pg
On first reading, you may want to skip many of the sections which
provide detailed information and look at only the overview and example
sections. Before using Kermit-GCOS, however, you
should go back and read the full writeup.
.sb 1.1.1.~What~is~Kermit?
Kermit is a protocol designed for reliable file transfer between
computers.
The transfer takes place through a standard RS-232 communications
port,
allowing implementation of Kermit transfer programs on most computers.
Although Kermit is technically the name of the transfer protocol,
it is common practice
to refer to both the protocol and programs which use the protocol
as Kermits;
this will be done through the remainder of this writeup.
.pg
Kermit development started at the Columbia University Center for Computing
Activities in 1981.
The primary developers were Bill Catchings
and Frank da Cruz.
Since that time the protocol has been extended and implemented for
many systems.
Persons interested in how the protocol works should read
articles in the June and July 1984 issues of
.ul
Byte
magazine which describe it in some detail.
.pg
In order to transfer a file with Kermit,
Kermit must be running on
both the sending and receiving computers.
One Kermit
(called "local Kermit")
must be able to establish the connection
with the other Kermit
(called "remote Kermit").
In the case of transfer between a microcomputer
and a mainframe this is generally done by the microcomputer Kermit
acting as a terminal as well as providing file transfer capability.
.pg
Microcomputer versions of Kermit are available from many bulletin
board systems. A tape containing all "known" versions of Kermit can
be obtained from Columbia University.

.sb 1.1.2.~Syntax~Conventions
To show the syntax of commands and responses
this writeup uses the following conventions:
.pg
Angle brackets surround a description of
what should be typed.
For example,
.jn
.jf
means to type a Kermit option;
it does
.ul
not
mean type " " literally.
.pg
Square brackets surround an optional item.
For example,
.jn
Kermit []
.jf
means type "Kermit",
optionally followed by some command.
If a "*" follows the closing square bracket,
it means "zero or more".
For example,
.jn
Kermit []*
.jf
means type "Kermit" followed by zero or more options.
.pg
Control sequences
are shown using
the convention that
"^^x" means
"hold the control key down,
press the 'x' key,
then release both keys."
For example,
when asked to type
.jn
^^]
.jf
hold the control key down and push the ] key.
.pg
When a keyword appears in a syntax description,
the letters which appear in uppercase must be typed.
The letters which appear in lower case
are optional.
Digits and special characters must be typed.
For example:
.jn
+OverWrite
.jf
indicates that "+", "O" and "W" MUST be typed;
the letters "ver" and "rite" are optional.
The minimum entry to invoke this option would be:
.jn
+ow
.jf
Note that the characters may be entered in either case;
the case in the syntax description is merely a method
to indicate which characters are required.
.sb 1.1.3.~GCOS~File~Formats
GCOS uses many different methods of storing and accessing files.
Since other systems do not necessarily support analogs of GCOS formats,
three file formats have been defined to handle all cases.
.pg
The default format is "Text".
This is the standard format used for text files in GCOS TSS.
When Kermit-GCOS transmits a text file, it removes GCOS file control
and record control words from the file and transmits a carriage-return,
line-feed sequence at the end of each record. It also deletes the
high (9th) bit of each nine-bit byte.
These bits are always zero in a text file
so no information is lost.
When Kermit-GCOS receives a file in text format, it adds a zero high (9th) bit
to each byte so that four fit evenly into each 36-bit Honeywell word.
It also converts the carriage-return, line-feed sequence at the end of
each record into Honeywell record control information and stores the
file in GCOS system standard TSS format.
Files transmitted to GCOS can
always be stored in text format even if the file content is eight-bit
data, such as a .COM or .EXE file from a microcomputer.
When transferred from GCOS to a system of the originating type, such
files will be restored exactly to their original form.
Text is the most convenient format to use for
files transferred to GCOS for archival purposes.
.pg
The second format is "BYtestream".
A bytestream file is the best format to use
when sending non-text (binary) files, such as eight-bit telemetry data,
from other systems to GCOS for processing on GCOS.
The data is stored with no record structure,
i.e. only the bytes received with no added "control" information.
As in text mode,
Kermit-GCOS adds a high-order zero bit to each incoming eight-bit
character, to align on nine-bit Honeywell byte boundaries with
four characters per 36-bit word.
The unused portion of the last 1280-byte block of the file is filled with
zeros (ASCII nulls).
When transmitting a bytestream file, Kermit-GCOS strips the high-order bit
from each 9-bit byte, and transmits the full file including any trailing
zeros (nulls) which pad the last block.
The Bytestream option automatically sets the +Random option
since bytestream files must be accessed in random (direct
access) mode.
.pg
The third format is "BItstream".
A bitstream file also contains data only, with no control information.
It is different from bytestream in that
each nine eight-bit bytes received are packed into two 36-bit Honeywell
words. During transmission, each pair of Honeywell words is unpacked
into nine eight-bit bytes.
This format permits transmitting
and receiving GCOS files, such as random libraries, which use all
36 bits in each word.
Bitstream format is useful for archiving binary GCOS files on other
systems. One of the other two formats should be used for most other
purposes. Bitstream files should be accessed in random (direct access)
mode.
Specifying Bitstream format automatically implies the +Random option.
.sb 1.1.4.~GCOS~Data~Transfer~Modes
Kermit-GCOS can operate in two communications modes. One mode
receives packets as standard ASCII input, with a carriage return
(decimal 13) used to end each packet; the other receives packets
using "paper-tape" mode, with an ASCII DC3 character (also known
as XOFF, ^^S, decimal 19, or hexadecimal 13)
used to end each packet.
Which mode you should use depends on your GCOS site's system configuration.
.pg
Between your local Kermit and Kermit-GCOS is a Honeywell
communications computer, called a front-end processor.
One of the Honeywell front-end software programs is called GRTS.
GRTS uses the at-sign (@) as a character delete code for normal input
and provides no way to change this.
For example, the character sequence "ABC@@D" would be received through
GRTS as "AD".
Since the Kermit protocol requires that all printable ASCII characters
(including @) can be sent and received,
by default Kermit-GCOS uses paper-tape mode to read packets.
In paper-tape mode, "@" is treated as a normal printing character.
In this mode, however, the end of input is indicated by an ASCII DC3
character (XOFF) instead of a carriage return.
This means that before beginning a file transfer you must set the
send end of line character for your local Kermit to this value.
.pg
Honeywell's newer front end software has the ability
to change the character delete code.
If you change it to a non-printing ASCII character
(e.g. backspace or delete)
then you need not use paper-tape mode.
For non-paper-tape input mode, your local send end of line character
should be a carriage return. This is the default for most versions
of Kermit.
To select this mode for Kermit-GCOS use the -TapeMode option which
is described in the option section below.
.pg
Unless you must operate in paper-tape mode, it is best to use the
-TapeMode option. Tape mode prohibits the use of XON/XOFF flow
control, since the XOFF control would also signal the end of a
packet. In general, GRTS does not support flow control; however,
if your site has implemented flow control for GRTS, sending a Kermit packet
while Kermit-GCOS is not in a receive state would lock the line. You
would then have to escape to interactive mode, type ^^Q^^D^^S to
regain control, and restart the file transfer from the beginning.
.pg
Flow control can also be a problem if your connection to GCOS is
through a network. To use tape mode through a
network it must not depend on XON/XOFF control for blocks the size
of Kermit packets (up to 96 characters).
You may need to set network parameters to pass XOFF as data. Consult
with local support staff or see local documentation if your
connection is through a network.
.pg
Finally, whenever GRTS is ready for input it sends an ASCII DC1
character. If your local Kermit has an option for DC1 (^^Q or XON)
handshaking, you should select it, especially if you are using tape mode.
.sb 1.2.1.~An~Overview~of~Kermit-GCOS
This section presents a summary of the features of Kermit-GCOS.
It assumes you are already familiar with
some basic information about GCOS time-sharing, such as how to log on
and off.
If you are not,
then first read appropriate documentation for these
topics.
.pg
Kermit-GCOS operates as a remote version only.
That is,
it never originates a connection.
It must be called by Kermit running on another system,
usually a microcomputer Kermit in local mode acting as a terminal.
.pg
Commands and options to control Kermit-GCOS can be supplied on
the command line, entered following prompts in interactive
mode, or sent from your local Kermit through the use of the
Kermit-GCOS server mode.
.pg
Multiple files can be transmitted by supplying a list of names
through the index file option. Separate file format options can be
given for each entry in the index file.
.pg
A working directory can be defined as the default location for
files to be sent or received. The working directory is internal to
Kermit-GCOS. It is not dependent on the working directory facility
introduced recently in GCOS.
.sb 1.2.2.~Invoking~Kermit-GCOS
To start Kermit-GCOS,
enter the following command line:
.jn
KERMit [] []*
.jf
where the ""
is an optional Kermit command.
If you do not specify a command,
Kermit will enter interactive mode,
prompting you for commands.
If you do specify a command,
Kermit will execute the command
and then end.
If options are given but no command,
Kermit sets the options
and enters interactive mode
(see
Kermit Options,
below).
.sb 1.2.3.~Kermit~Commands
Kermit-GCOS recognizes the following commands:
.sp
.oc ?~--~Print~a~List~of~Commands~Recognized
Typing a "?" as a command will cause a list
of recognized commands to be printed.
.sp
.oc Done~--~Exit~Kermit
Done
.sp
The Done command exits Kermit.
You may also type "Exit" or "Quit".
.sp
.oc Help~--~Provide~Basic~Explanations
Help
.br
Help
.sp
The Help command prints information about the
or specified.
Specifically,
the relevant portion of this document is printed.
.sp
.oc Receive~--~Receive~a~file
Receive [ ]*
.sp
The Receive command causes Kermit-GCOS
to wait for files to be sent from the local Kermit.
The files will be created or accessed according to the current
option settings,
unless overridden on the command line
(see
Kermit Options,
below).
.sp
.oc SENd~--~Send~a~File
SENd []* []*
.sp
A is either the name of a file to send
or "indeX=filename"
where the file contains Kermit SENd command options and filespecs.
.pg
The SENd command causes Kermit-GCOS
to send files to the local Kermit.
The files will be sent according to the current option settings,
unless overridden on the command line
or in an index file.
Kermit-GCOS will wait for the number of seconds
specified in the Delay option
before starting to send the files.
This allows you time to escape back to your local Kermit
and type RECEIVE.
.sp
.oc SERver~--~Enter~Server~Mode
SERver []*
.sp
The SERver command causes Kermit-GCOS
to enter server mode.
While in server mode,
Kermit-GCOS will wait for commands from
your local Kermit.
When a command is received,
it is executed.
Server mode is the preferred mode
of operation,
although not all local Kermits support it.
If your local Kermit supports server mode,
you should use it.
The use of server mode is detailed more fully below.
.sp
.oc SET~--~Set~Kermit~Options
SET [ ]*
.sp
The SET command causes Kermit to set its options
as you specify on the command line.
Normally,
options given on a command line
apply only to that command.
A SET command causes them to change until a later SET command is given.
.sp
.oc STatus~--~Print~Options~Status
STatus
.sp
The STatus command causes Kermit-GCOS
to print a list of the current option settings.
.in 0
.an (pgse) 0
.sb 1.2.4.~Kermit~Options
.an (pgse) 1
The following options are recognized (default settings are shown in
parentheses):
.jn
?
CWD=pathname
DeBug=function (Off)
Delay=nn (10)
(+|-)Discard (-)
Format=fileformat (Text)
indeX=filename
(+|-)OverWrite (-)
(+|-)Permanent (+)
(+|-)Random (-)
SendEndOfLine=nn (13)
SendStartofPacket=nn (1)
(+|-)TapeMode (+)
.jf
.ne 10
.sp
Options:
.sp
.oc ?
causes a list of the allowed options for the command given
to be printed.
.oc CWD=pathname
sets the Kermit working directory to the specified path. By
default, your working directory is your USERID. It can be
changed to any catalog or subcatalog where you want files
placed by default.
.oc DeBug=function
specifies how much debugging information is to be
written to the debug file "kerm*dbg".
The default is "Off", which means that no debugging information
will be written.
"States" causes the current protocol state to be written
when it changes.
"Packets" causes each packet sent or received to be written.
"All" causes all possible debug information to be written.
This information is rarely useful,
unless you suspect that your communications line
is noisy and wish to inspect what is being sent.
.oc Delay=nn
causes Kermit to wait nn seconds before sending the first packet
when using the SENd command.
The default is 10 seconds.
.oc +Discard
causes Kermit to discard an incomplete transmission.
If you interrupt the transmission of a file,
the file will not be created on GCOS.
If -OverWrite is in effect,
the previous contents will be unchanged.
.oc Format=fileformat
causes any file transferred in either direction
to be treated according to the file format specified.
The formats are "Text", "BYtestream", and "BItstream".
See the section on file formats.
The default is Text.
.oc indeX=filename
specifies a file containing
Kermit SENd commands and options,
one command per line.
This option permits sending multiple files with a single command.
This option is analgous to the "wildcard send" feature of some Kermits
in that it allows transfering multiple files easily. It
was selected for Kermit-GCOS because GCOS does not support wildcard names,
and allowing an index file of names provides additional
flexiblity in sending dissimilar names.
This option is only meaningful when used with the Kermit SENd command,
or from "GET" commands received in Server Mode.
Only the "Format=", +Random, +Discard,
-Permanent and +OverWrite options
may be used in index files.
.oc +OverWrite
causes an existing file of the same name to be overwritten.
The default is -OverWrite,
which causes the incoming file to be renamed
to avoid conflicts.
The file is renamed by appending "_n"
to the file,
where n is the smallest digit not resulting in a clash.
If the filename is too long,
the underscore will be omitted.
If the filename is still too long,
characters will be deleted from the end
until it fits.
.oc -Permanent
causes Kermit to use standard GCOS rules
for creating/accessing files.
So if there are no slashes or dollar signs
in the filename and if the filename is less than or
equal to eight characters long,
and if a quick access file of the same name does not
already exist,
the file will be created as temporary.
Otherwise it will be created as permanent.
If +Permanent
(the default)
is used,
the file will always be created/accessed as permanent.
.oc +Random
causes Kermit to access the file as random.
The default is sequential, or -Random.
For non-text files, +Random must be specified.
.oc SendEndOfLine=nn
causes Kermit to terminate its outgoing packets
with the ASCII character whose decimal value is nn.
Example:
SendEndOfLine=26
would cause Kermit to terminate its outgoing packets with a ^^Z
(decimal ASCII value = 26).
The default is carriage return
(value = 13).
.oc SendStartofPacket=nn
causes Kermit to start its outgoing packets
with the ASCII character whose decimal value is nn.
Example:
SendStartofPacket=26
would cause Kermit to start its outgoing packets
with a ^^Z
(decimal ASCII value = 26).
The default is ^^A (value = 1).
.oc -TapeMode
causes Kermit to use standard GCOS terminal input mode
instead of "paper tape" input mode to read incoming packets.
See the GCOS Data Transfer Modes section, above, for more information.
The default, +tapemode, must be used at sites where the
character delete code is "@" because Kermit requires the
ability to send and receive all printable ASCII characters.
.in 0
.sb 1.2.5.~Server~Mode
Kermit-GCOS server mode enables Kermit-GCOS to receive commands
through packets from your local Kermit if it supports server mode.
This eliminates the need to switch back and forth between
terminal mode and local mode each time you start a file transfer.
.pg
In addition to the file transfer commands, GET and SEND,
Kermit-GCOS Server mode supports
several generic commands defined in the Kermit protocol.
A short list of the commands as given
in the Kermit Protocol manual follows.
Be warned that not all Kermits support all
Server commands,
and even if a Kermit does support a command,
it may not be invoked with the same name
as another Kermit's.
For example,
the "erase" command,
which releases files,
is called the "remote delete" command
by Kermit-MS.
Read the documentation for your microcomputer Kermit
for details.
.sp
The following server commands are supported:
.jn
CWD - Change Working Directory
Erase - Release a file
Finish - Terminate Server Mode
Get - Receive a file from GCOS
Logout - Terminate Kermit and Disconnect from TSS
Send - Send a file to GCOS
Status - Query Kermit-GCOS Status
Type - List a file.
.jf
The following descriptions
of server mode commands
apply to Kermit-MS.
.sp
.oc Bye
This command ends your GCOS session for you
and in addition, exits Kermit.
You will then be back in MS-DOS.
.sp
.oc CWD
This command is used to change your working directory
(catalog).
By default,
your working directory is your userid,
so any files that you send will be
created under your userid but not under any catalog.
Suppose you wanted to send your files to a subcatalog on
your account called "/microfiles".
You would enter
.jn
REMote CWD /microfiles
.jf
in Kermit-MS,
enter a RETURN to the "Password:" prompt,
and then use the "send" command.
Any files sent would be placed under the "/microfiles" catalog.
Typing "REMote~CWD" with no catalog specified
causes your current working catalog to be displayed.
.sp
.oc Erase
Erase is used to delete a file from your GCOS current working directory.
You must enter
.jn
REMote DELete
.jf
to invoke this command.
Erasing multiple files with one command is not supported.
.sp
.oc Finish
This command tells Kermit-GCOS to exit server mode.
This is useful if you want to resume using Kermit-MS as
a terminal after doing some file transfers.
Just enter "Finish",
then "connect",
then enter a RETURN and you will be back
at star-level on GCOS.
.sp
.oc Get
To download (get) a file from GCOS to the microcomputer,
enter
.jn
GET pathname
.jf
where "pathname" specifies the GCOS file you want to get.
The file name at the end of "pathname"
will be used as the MS-DOS file name.
To give the MS-DOS file a different name,
enter
.jn
GET
.jf
Kermit-MS will prompt for "Remote~Source~File:~".
You should respond with the pathname of the GCOS file.
Kermit-MS will then prompt for "Local~Destination~File:~".
You should respond with the MS-DOS name under which
you wish the file to be saved.
The remote file may be an index file.
If you type
.jn
get index=/mylist
.jf
this indicates that the GCOS file "/mylist" contains
the names of files to be sent.
.sp
.oc Logout
This command ends your GCOS session for you but
does not exit Kermit.
.sp
.oc Send
To upload (send) a file from Kermit-MS to Kermit-GCOS,
enter
.jn
SEND [ []*]
.jf
where "" may contain MS-DOS wild-card characters to
specify more than one file.
For example,
.jn
SEND *.txt
.jf
will send all files that have the extension "txt".
Since the question mark ("?") is used within Kermit-MS
to obtain help,
you must use the equal sign ("=") for single-character
wild-cards.
.pg
The may be a list of filenames
and index files
(see SEND in the commands section).
.sp
.oc Status
This command displays the current status of Kermit-GCOS.
This Server mode command is not currently
supported by Kermit-MS,
so there is no way to invoke it.
.sp
.oc Type
To display the contents of a GCOS file,
enter
.jn
REMote TYPE
.jf
and the file will be printed,
maddenly slowly,
on your screen.
.in 0
.br
.sb 1.3.1.~Sample~Kermit~Sessions
You must always begin a Kermit transfer by starting your local
Kermit and setting local options, then connecting to TSS.
The local options available and how to set them will depend on
what computer and version of Kermit you are using.
However, some options must
be set correctly before a connection can be established
and before file transfer is possible. These include baud rate,
local end of line, and local echo.
.pg
The following
sample session with Kermit-MS and Kermit-GCOS
downloads (gets) a file from GCOS
to MS-DOS.
The example assumes that drive "A"
is your default drive
and that it contains a disk with
the MSKERMIT program.
User input is underlined.
The sequence ^^]C refers
to "control-]" followed by "C",
i.e. hold the control key down
and press the ] key
then release the control key and type a "C".
For other versions of microcomputer Kermit, the details will be different.
.pg
This session transfers the GCOS file "myfile" under subcatalog "mycat"
of your logon userid to the MS-DOS file "dosfile.txt" using a 1200 baud
connection to a GCOS system which uses "@" as the character
delete symbol.

.sb 1.4.1.~Bootstrapping~Kermit-GCOS
There are three different ways which you may obtain Kermit-GCOS:
through the HLSUA library, from Columbia University, or over a
telecommunications line.

The easiest is through the HLSUA library as a FILSYS save tape.
Installation instructions accompany the tape.
.pg
The Columbia University CUCCA Kermit distribution tape contains
five files for Kermit-GCOS. These are:

HDPS8.FTN 122 Fortran program to convert .PAK file to H*
All five files are in text format.
The first step in installing Kermit-GCOS is, of course, to copy these
files from the tape to disk.
.pg
Since the Columbia tape cannot contain a Honeywell
random binary file, Kermit is provided in packed
ASCII text form (HDPS8.PAK) along with a Fortran program (HDPS8.FTN)
which documents the packed format and converts the packed file
into Honeywell executable (H*) format.
Create a 65 block random file to hold the H* and
run the following job:
$$t(;)
$;ident;userid,banner
$;option;fortran
$;use;.gtlit
$;fortran;ascii,xref,optz
$$select(userid/hdps8.ftn)
$;execute
$;prmfl;01,w,r,userid/kermit
$;prmfl;02,r,s,userid/hdps8.pak
$;endjob
.pg
After this job runs, copy file "userid/kermit" to "cmdlib/kerm" to
make Kermit available through the command library.
.pg
The packed text file contains a checksum byte on each line, and does not
contain and GRTS character delete codes (@), so it can be sent to
GCOS over a telecommuncations connection using any ASCII file
transfer program. The installation process
for generating an H* file is the same as described above.
The program will print warning messages if any checksum errors are
encountered.
.sb 1.4.2.~Setting~Local~Options
Kermit-GCOS contains three flags to enable setting local options.
As distributed, all three flags are set to false.
The flags allow setting the default working directory to the
current TSS working directory instead of the USERID when entering
Kermit, enabling the server command for remote directory, and enabling
the server command for remote space information. You should enable
remote directory only if you have the LC command which is distributed
with the B language package written at the University of Waterloo.
You should enable the remote space command only if you have replaced
the standard Honeywell SMCL command with a version which permits
directing output to a file with "SMCL >filename".
You should enable the working directory switch only if your site
has enabled the Honeywell TSS working directory feature. Note that
Kermit working directories can be used regardless of the setting of
this switch-- it controls only the default working directory on
entry to Kermit.
.pg
After running HGUNPACK to convert the Kermit packed text file into
an H*, you can use LODX to modify the flag locations to match local
capabilities. The flag addresses are
Address (Octal) Content
000153 wat_lc
000154 wat_smcl
000155 wat_cwd
All values are initially false (zero).
The following example enables remote directory and working directory
initialization.
*_l_o_d_x_ _/_k_e_r_m_i_t
patch, save or run? _p
?_1_5_3_ _1
?_1_5_5_ _1
?_<_r_e_t_u_r_n_>
patch, save or run? _s
patch, save or run?_<_r_e_t_u_r_n_>
*
.pg
These values are declared at the beginning of the EXTRN section of
the B source code.
You can adjust the settings for your site there if you recompile
the source code.
.pg
Note that the user documentation describes Kermit with the default
(false) settings for all three switches.
That is, it does not list REMOTE DIRECTORY and REMOTE SPACE as
available server commands, and states that the working directory
is initially set to the USERID. If you modify these flags, update
the documentation.
