USING KERMIT AS A TERMINAL EMULATION PROGRAM WITH PICK
By David L. Clark, History Database
Kermit is a terminal emulation and communications program distributed
free of
charge by Columbia University. The use of Kermit for both terminal
emulation
and communications is thoroughly documented in the book Using MS-DOS
Kermit:
Connecting Your PC to the Electronic World, by Christine M. Gianone,
published
by Digital Press. A disk containing the Kermit program is included with
the
book. Copies of Kermit and additional documenation may be obtained from
Kermit
Distribution, Columbia University Center for Computing Activities, 612
West
115th Street, New York, NY 10025, (212) 854-3703.
Steps to Take for Terminal Emulation
To use Kermit as a terminal emulation program with Pick, take the
following
steps:
1.
Copy the files on the Kermit disk, placed in the A Drive of
an
IBM PC compatible computer, to the C Drive hard disk with the following
command given in DOS:
C> COPY A:*.*
2.
The Kermit program is contained in the file "Kermit.exe".
When
Kermit is started, the program looks for an initialization file with the
name
"MSKermit.ini". I have supplied here the file "MSKermit.hd" which
contains a
complete set of initialization instructions intended for use with the
full-screen editor of the History Database program, and the file
"MSKermit.pck" which contains a very minimal set of initialization
instructions intended for use with generic Pick. The History Database
version
moves Kermit functions away from keys which might be pressed
accidentally,
such as PG UP and PG DN, to CONTROL-ALT-Key combinations. Both
initialization
files are presented in detail below. To change back and forth between the
two
instruction sets give the following commands in DOS:
To use the complete set give the command:
C> COPY MSKermit.hd MSKermit.ini
To use the minimal set give the command:
C> COPY MSKermit.pck MSKermit.ini
3.
Kermit emulates the VT320 terminal. Use the DEFINE-TERMINAL
command, supplied by Pick Systems, to define the new terminal for the
Pick
operating system. The DEFINE-TERMINAL command and the parameters to use
are
presented below. Use either Pick's ACC file, which stores default
parameters
for each port, or the TERM command given from the affected port, to set
the
port to the appropriate terminal type. For example, if you used
DEFINE-TERMINAL to create a terminal type "Z", after starting Kermit and
logging onto Pick you would give the command:
> TERM Z
4.
Use Pick's SET-BAUD and XCS-ON commands to set the baud rate
for the port to match that in Kermit's initialization file. The rate is
19200
on the file supplied here. Use the XCS-ON command to allow use of the IBM
Extended ASCII graphics characters, if you wish to use those characters.
Follow each command with the port number. For example, for port number
one:
> SET-BAUD 1,19200
> XCS-ON 1
5.
Connect the host computer and the IBM PC with Kermit loaded
with a null modem serial cable.
6.
On the IBM PC, begin the Kermit program with the command:
C> Kermit
7.
To wake up Pick, just
terminal, press the ENTER key on
logon message appears, give your
give
the TERM command to set the port
8.
as you would after turning on a
the IBM PC running Kermit. When the Pick
account name. After you have logged on,
to the appropriate terminal type.
To see the communications parameters used press CONTROL-ALT-S
if you employed the full MSKermit.hd instruction set, or ALT-S if you
employed
the minimal MSKermit.pck instruction set.
9.
To print a copy of a Pick screen, connect a printer to the
parallel port of the IBM PC running Kermit and press the Print Screen
key. To
dump a copy of the Pick screen to the DOS file "Kermit.scn" press
SHIFT-CONTROL-ALT-END if you employed the full MSKermit.hd instruction
set, or
CONTROL-END if you employed the minimal MSKermit.pck instruction set.
Each
time that you give the dump command, the current screen will be added to
the
DOS Kermit.scn file, separated from previous screens by a form feed
character.
To roll the screen up and down, press CONTROL-ALT-PG UP and CONTROL-ALTPG DN
if you employed MSKermit.hd or PG UP and PG DN if you employed
MSKermit.pck.
10.
To give Kermit commands, call up the "MS-Kermit>" prompt by
pressing CONTROL-ALT-X if you employed the full MSKermit.hd instruction
set,
or ALT-X if you employed the minimal MSKermit.pck instruction set. Give
Kermit
commands at the "MS-Kermit>" prompt only. All of the commands shown below
for
the MSKermit.hd and MSKermit.pck instruction sets are Kermit commands
that
could be given or modified at the "MS-Kermit>" prompt. The comments
included
with the instruction sets include alternate versions of the commands. For
example, to see the communication and terminal definitions used, at the
Kermit
prompt you would give the commands SHOW COMM and SHOW TERM. To reconnect
to
Pick you would then give the Kermit command CONNECT:
MS-Kermit> SHOW COMM
MS-Kermit> SHOW TERM
MS-Kermit> CONNECT
11.
When you are finished, give the OFF command in Pick, just as
you would from a terminal:
> OFF
12.
To exit from Kermit and return to the DOS prompt, give the
EXIT command at the Kermit prompt. Be to give OFF from Pick before you
EXIT
from Kermit.
MS-Kermit> EXIT
The Kermit Initialization File
Kermit looks for an initialization file with the name "MSKermit.ini". Two
versions are presented here. The file "MSKERMIT.HD" contains a complete
set of
initialization instructions intended for use with the full-screen editor
of
the History Database program. The file "MSKERMIT.PCK" contains a very
minimal
set of initialization instructions intended for use with generic Pick.
The
History Database version moves Kermit functions away from keys which
might be
pressed accidentally to CONTROL-ALT-Key combinations. Copy the file that
you
wish to use to the filename "MSKERMIT.INI". In the files presented
below,
note that the semicolon is used to begin a comment in Kermit. ASCII
characters
may be employed by preceding the ASCII number with a backslash. For
example,
to send a Carriage Return -- Line Feed: "\13\10". To reset a key, the
scan
code is followed by the ASCII value. A table of IBM PC scan codes appears
in
Using MS-DOS Kermit. The form of the command is:
SET KEY \scan-code \ascii
All of the commands shown are Kermit commands which can be given from the
"MS-Kermit>" prompt. Alternatives to the commands used are also
presented.

Use the DEFINE-TERMINAL Command to Define a New Terminal for Pick (For
more
information on DEFINE-TERMINAL, see: Programming with IBM PC Basic and
the
Pick Database System, by David L. Clark, page 300.) The DEFINE-TERMINAL
command may be used to create definitions for terminals not already
defined on
the system. To begin the procedure, at Pick TCL give the command:
DEFINE-TERMINAL
The system will take half a minute to round up all of the terminal
definitions
available, and then will display DEFINE-TERMINAL's main menu. DEFINETERMINAL

presented with the named terminal's characteristics. Only one terminal is
displayed at a time. For this example three terminals have been shown
together. The MM-MON definition for the memory-mapped monitor of an IBM
PC
used as the main computer was supplied by the Pick Systems. The WYSE.60

The list of choices is divided between two screens. After each screen is
displayed, the DEFINE-TERMINAL procedure prompts:
Modify lines?
When the answer to the DEFINE-TERMINAL program's "Modify lines?" question
is
finally "NO", the program asks if the table is correct. If the answer is
"YES"
the procedure tries to compile the table. If there is an error, an error
message appears. Otherwise, the procedure returns to the first screen. To
store the new configuration, enter "FI" for File Item. The Kermit
terminal
emulation program emulates the VT320 terminal. The DEFINE-TERMINAL
definition
presented here for use with Kermit implements a 25-line screen, rather
than
the standard 24-line screen of the VT320 terminal. The size of the screen
has
been defined as "80,25" and Escape codes have been added to the Clear
Screen
and Home and the Clear to End of Page instructions to go to the 25th line
and
clear it. To use only a 24-line screen, define the screen size as "80,24"
and
eliminate the extra Escape codes ESC "[25;0H" ESC "[2K".
