- Joost ,
We have no idea what version of PK232 you are using but Ive a bad feeling
Ive seen this problem several times before..
PK232 firmware prior to DEC 1988 does not support KISS even thought it is
Do a RESTART command and see what version of firmware you have. It should
look like this
AEA PK-232 Data Controller

The Release date may be Earlier than DEC 88 I fear on your PK232
As I say .. I have not found any firmware version prior to DECember 1988
that really supports KISS..
To prove this goto your Hyperterminal again and once you have the cmd:
PA to put it into PAcket mode if it isnt allready.
With my plain vanilla Non MBX PK232 the CMD: Prompt now dissapears
If the cmd: is still there then your PK232 is not KISS capable.
Ive never seen a PK232 that needs a RESTART after a KISS ON but it would not
hurt anyway because the PK232 should be in KISS mode at that time and ALL
text command inputs from Hyperterm will be ignored anyway.
TNCs like MFJs and TNC2 clones need the Restart after the KISS On command
So if your PK232 is not KISS capable then what? It needs a Firmware upgrade.
Ive done this on at least 2 PK232's .. You need a EPROM burner and possibly
The Chips U4,U5,U2,U3 are involved.
Both Eproms U2,U3 are new firmware.
If either U4 or U5 are missing you will need another RAM chip. These are
6264 RAMs which are hard to get. I have seen some PK232s with both RAM chips
onboard prior to upgrade. It may be possible to run KISS without both RAM
chips as well but I dont know really.
If you have a friend with a PK232 that does work in KISS mode then get
together and pull off the covers and compare the 2 PK232s .. It will be
obvious if there are any differences with these chips. The 2 Eproms have to
be changed to 27256 or 27C256 chips instead of 1x27256 and 1x27128
Hope this helps. Maybee I am way off here but Ive seen this so many times
now and it keeps comming up on various Mail groups as people dig out their
old PK232s that used to work fine (except they never used KISS mode) ..
I have a copy of the PK232 firmware binaries for the Eproms and they are
also freely available off the internet in various places..

I am most grateful to John, G8BPQ and Mike, N9PMO, for assisting me
in getting BPQ32 and FBB32 up and running and talking to each other.
What I expected to be a piece of cake, activating the PK232 and
the VHF transceiver, turns out te be another hurdle.
- PC, PK232 and the radio are wired up correctly.
- On the pc, I open up Hyper Terminal and connect to the PK232.
After typing the * (star) I enter a string of commands.
I found five different strings to get the PK232 in KISS mode but
none of them seems to work ... probably something else is wrong.
After typing in
Hyper Terminal displays whatever activity there is on the channel.
The strings of commands normally end in
Next I close Hyper Terminal .... and wonder whether the commands
are retained in the PK232?
FBB is activated which opens BPQ32 instantly.
In the 'Port' section of BPQ I have the following:
PORTNUM=1 ; Optional but sets port number if stated
ID=144.625 1200 Baud ; Displayed by PORT command
TYPE=ASYNC ; EXTERNAL = calls an external module
IOADDR=1 ; 3F8 serial 1, 2F8H serial
CHANNEL=A ; A=1, B=2 etc. - required param
QUALITY=10 ; Setting to 0 stops node broadcasts
MAXFRAME=1 ; Max outstanding frames (1 through 7)
FRACK=7000 ; Level 2 timeout in miliseconds
RESPTIME=2000 ; Level 2 delayed ack timer in milliseconds
RETRIES=7 ; Level 2 maximum retry value
PACLEN=225 ; Default max packet length for this port
UNPROTO=MAIL, ZS0HIL-2 ; DEFAULT UNPROTO ADDR (no 'v' required)
I can hear Packet activity on the radio channel and it shows on the
PK232 Tune bar but no display of what is going on on the Monitor
functions in FBB and BPQTerminal.
Beacon and unproto signals are generated but the VHF transceiver is
It baffles me and your assistance would be highly appreciated.
- With PROTOCOL=KISS, the FULLDUP parameter is passed to the TNC, and all the KISS implementations I know of will obey the param (ie not transmit if carrier is present and FULLDUP=0). Also all that I know will operate true full duplex (simultaneous transmit and receive) if the frequencies are far enough apart (probably crossband, but with good enough cavity filters could be in same band), No handshaking signals are used, so a 3 wire cable is fine.With PROTCOL=NETROM, FULLDUP controls the link between the PC and TNC(s). With BPQ32 it has to be set to 1, and only supports 1 TNC, but with the old DOS BPQCODE you could set FULLDUP=0, and connect a stack of NET/ROM TNC's via a diode matrix. In this case the RTS and CTS lines control the matrix.73,John G8BPQ-----Original Message-----

Subject: Re: [BPQ32] Full DCD signal but will still transmitI am quite interested in this issue. I have always used the JKISS or BPQKISS ROM, with minimal wiring (RX,TX and GND) and FULLDUP=0, and have never noticed the TNC (MFJ1270C's) stomp on a signal being received (with the DCD led illuminated) .
This does bring up the possibility that if the RX and TX frequencies are far removed, it may be possible to operate full duplex. I had thought the hardware prevented this, but perhaps not?
With PROTOCOL=NETROM is is necessary that FULLDUP=1 for the interface to function. Might it then transmit with DCD on and thus stomp on the received packet?
While I have always used the minimal cabling, might full cabling be required in some cases?

Subject: RE: [BPQ32] Full DCD signal but will still transmitDave,Setting FULLDUP=0 in the port definition should stop it, although this relies on the TNC obeying the relevant KISS command.73,John-----Original Message-----

Subject: [BPQ32] Full DCD signal but will still transmitMy BPQ ports will transmit on top of someone even if the TNC shows it havinga full good DCD. IT will just tromp on them anyway.In the old BPQ (which is on my dead machine) I seem to remember a portcommand to stop that. What was it?Thanks,73 Daven4zkf
