PK232COM READ.ME Page 1
Read G3ZCZ.LAN for an overview of the PK232COM concept.
The PK232COM files are described in the PK232COM.DOC file.
YOU MUST EDIT THE PK232COM.SYS FILE BEFORE YOU CAN PUT THE
PROGRAM ON THE AIR FOR THE FIRST TIME. Use your word processor in
the NON-Document mode.
This file tells PK232COM what is special about your station. You
must edit the first 10 lines as a minimum, then read the
documentation file section 4.3 for the remaining lines.
The contents of the file are as follows.
4.3.1 The first line.
The first line contains your callsign.
Please do not use G8BTB. Replace G8BTB with
yours. You may use / characters if you wish.
This is the call sign that will be used in the
non- Packet modes. You may thus use "portable
designators" such as G3ZCZ/A, G3ZCZ/W3 or
G3ZCZ/4X, which you cannot do in Packet. IF YOU
DON'T CHANGE THE CALL SIGN, YOU WILL GET AN ERROR
MESSAGE AND THE PROGRAM WILL NOT RUN.
This is the call that will be monitored for in the
Digipeat monitoring mode. In this mode which is
toggled on and off by the Alt F key, if someone
uses you as a digipeater while you are not
connected to anyone else, the event will be logged
to disk. This mode will only work if your
callsign as stored in this line is a valid
(uppercase only) packet callsign.
For example, in the PK-232, if the callsign is
G3ZCZ then the sequence >G3ZCZ> will be recognised
as a digipeat and the event logged. Thus for
example 4X6AA*>G3ZCZ>4Z4ZB would be logged as a
digipeat event.
Now if the callsign in this line is G3ZCZ/4X then
the event will not be recognised as a digireat
because the computer would be checking for a
G3ZCZ/4X in the packet header and it would never
see G3ZCZ/4X. This option is inhibited for
reciprocal callsign operators due to the AX2.5
protocol itself.
If you have a / character in your callsign, and
use the base call for packet identifying the
location in the CQ text, then the function will
work if you place the "portable location" as a
(c) Joe Kasser G3ZCZ
PK232COM READ.ME Page 2
suffix. For example, if the call is G3ZCZ/4X and
the packet identification is G3ZCZ, then the
digipeat monitor will work. If the call was
entered as 4X/G3ZCZ the digipeat monitor would
check for 4X and would not appear to work.
Store your callsign using UPPERCASE characters if
you want this option to work (IE. G3ZCZ). If you
use lower case (ie. g3zcz), the option will not be
enabled as recognition will never take place. The
PK232 automatically converts case to upper case in
the non packet communications modes.
If you are using an SSID (eg. G3ZCZ-8) in the
packet communications mode, you should enter the
whole call INCLUDING the SSID.
4.3.2 The second line.
The second line contains the AMTOR SELCAL
configured for your callsign. You use it again
later to tell the PK232 what the SELCAL is. This
line just tells it to PK232COM.
4.3.3 The third line.
The third line contains the line of text
transmitted by the PK-232 in a CQ call (in any
mode except for MORSE). Think of this message as a
CQTEXT line. Edit this line as well.
4.3.4 The fourth and fifth lines
The band and power information are set up from the
default values stored in the configuration file
PK232COM.SYS. They are displayed in the status
window. If you operate on another band or your
transmitter uses a different power level change
the default values in the file to reflect your
custom default state.
The fourth line contains the band information.
The default value is 2 for 2 Meters. Use the
Meter value for the band to keep the display
correct.
The fifth line contains the value for the
transmitter power. The default value is 10 for 10
watts.
4.3.5 The sixth line
The sixth line contains a number which tells the
program how long to wait before transmitting a CQ
call when in the beacon (automatic) mode. A value
(c) Joe Kasser G3ZCZ
PK232COM READ.ME Page 3
of 4 corresponds to about 2 minutes. This value
of time will vary depending on the clock speed of
your computer. You may have to experiment with
different values. The default value is 0 which
inhibits the beacon mode.
4.3.6 The seventh Line
The seventh line configures the LAN store and
forward capacity of the system also known as the
Message Relay Capability. If it is a '0' (default
state) your computer will not accept messages for
forwarding. If it is a '1', it will. See Appen-
dix 2 for details about LANs.
Remember, if you configure your computer to store
and forward messages, you have a moral obligation
to deliver them.
The status of this function shows up as an [R] in
your status display and in the connect message
which is transmitted to the other station at con-
nect time, as an 'R' suffix to the message when
active.
4.3.7 The eighth line
This line contains the default Communications
port. The default value is 1. You must leave it
set to 1. THIS VERSION OF PK232COM CAN ONLY BE
USED WITH COMM1.
4.3.8 The ninth line (TNC type)
This line tells the program which TNC you are
using. The PK232 command set is slightly dif-
ferent to those of TNC2 in the packet mode. Thus
the command dialog has to be changed somewhat to
make the 'SOLO, TRAFFIC, CQ/BEACON and MAIL' ter-
minal modes work correctly for different TNC's.
NOTE that program does not check the TNC in the
Non Packet modes, so for example if you try to set
a TNC2 to AMTOR, PK232COM will send the PK232
commands to the TNC2 which should then return an
error message.
Valid TNC's are PK232
TNC1
TNC2 (don't type the '.').
The TNC2 used to test PK232COM 1.41 was an MFJ
1274.
4.3.9 The Tenth line (Terminal Baud Rate).
This line tells PK232COM what baud rate the TNC
(c) Joe Kasser G3ZCZ
PK232COM READ.ME Page 4
is set to. This is the baudrate on the RS-232 line
between the TNC and the computer. Valid baud
rates for PK232COM are 1200, 2400, 4800 and 9600.
If you specify something else PK232COM will
default to 1200.
If the TNC does not use an interrupt driven serial
port you may experience problems when using baud
rates greater than 1200. The PK-232 does not like
baud rates faster than 2400, and sometimes not
even that. Use 1200 until you have tested and are
sure that a faster one will work.
This program has been tested on a TNC2 using a
terminal baud rate of 9600 bauds and worked
correctly.
4.3.10 The QTC _Snatch or Automatic Connect Attempt
Flag.
If the value entered on this line is a 1, then the
QTC_Snatch Flag is enabled. if the value on the
line is a 0, then the flag is disabled.
If the QTC_Snatch flag is enabled, PK232COM scans
the contents of packets appearing in the Inwindow
on the screen while the terminal is disconnected.
Should it recognise the three text strings
'PK232COM', ':QTC:', and 'your callsign' in the
packet, it will then issue a connect request to
the callsign of the PK232COM station that origin-
ated the beacon transmission. If the connect is
made, the other station will send you the message
automatically which PK232COM will capture to disc.
The connect will time out and terminate a few
minutes later.
Hopefully it will not try to connect to you if it
hears your beacon with your call in it (someone
left you a message) via a digipeater.
The normal connect request will be made DIRECT to
the station. A digipeat path will not be invoked
as this feature is designed to trigger a normally
silent station standing by on the LAN (good
operating practice). If you expect messages from
stations you can only connect with via a digi-
peater, place the path in your PK232COM.DIR
directory file. It should be there anyhow if you
connect to the station regulaly. For example, if
you expect messages from 4Z4ZB whom you can only
work if digipeated via 4X1AA then place an entry
like
4Z4ZB 4Z4ZB V 4X1AA
in the PK232COM.DIR file.

4.3.11 The remaining lines
The remaining lines contain commands to the PK-
232. For further information about them refer to
the TNC manual. The example in the PK232COM.SYS
file is as follows.
CONSTAMP ON
CHCALL ON
CHDOUBLE ON
CMSG ON
daystamp on
DCD ON
eas on
echo off
flow off
newmode on
NUCR ON
nulf on
If you use a different TNC (other than the PK232) you will
have to edit this command list.
NOTES to a YAPP user.
PK232COM uses the PK232 in a different configuration to the way
that YAPP does. In particular, PK232COM uses software flow
control.
To facilitate conversion from YAPP to PK232COM a YAPP.CNF file is
provided in this package. YAPP.CNF is a configuration file for
YAPP Version 2 that will configure the PK232 for YAPP and then
back to PK232COM.
If you are currently using YAPP, replace your YAPP.CNF file with
this one and load YAPP. Then terminate the program in the normal
manner by using the Alt-X key. You should then be able to load
and run PK232COM without any problems. Each time you sub-
sequently want to run YAPP, YAPP will set up the PK232, execute
and then reconfigure the PK232 back for PK232COM.
PK232COM resets the PK232 configuration depending on which mode
it is working in.
If you are using a YAPP.DIR file, rename it to PK232COM.DIR.
My system is a PC Clone which uses a Hercules Clone display card.
It has also run on an IBM-PC with a CGA adaptor/color monitor, a
clone with turbo in operation and an AT clone.
