Hi Ross --
There is a timer in the KISS firmware, that restarts the TNC after
a couple of minutes of no-activity. There is an un-documented
KISS command that will disable this annoying restart timer. You
need to send the 3-byte sequence $C0,$FD,$C0 to the TNC, while in
KISS mode, and it won't restart itself after that.
I put the command 'comm ax0 "\300\375\300" ' into my autoexec.nos,
and that sends the 3 bytes to the TNC ( I run JNOS 1.10 )
73, Mark.

Can someone tell me what is going on here?
The CON and STA LEDs blink three times in unison, just like when the TNC is
turned on, but they do this periodically while the TNC is running.
The gory details: tnc is an MFJ-1270B, firmware in socket U23 is labelled
"TNC2 1.1.8" (in a 27c256), U24 is empty, U25 has an HM62256LP-10, the chip
in U6 is labelled "Copyright 1985 SYSTEK STATE 1.09". The pcb is says "TNC2
Rev 2". JMP4 is open, JMP5 is closed, JMP7 is open, JMP8 is closed, JMP9 all
pins open, JMP11 is open, and JMP12 connects pins 1 and 2. As US Senator
Alphonese Dimato (sp?) (R-NY) said yesterday, "The facts are irrelevant."
There is one hardware mod that was done by persons unknown. A 1000 uf cap
has been added between R57 and the tab on Q10 (T624); from there, a 560 ohm
resistorn added to JMP J. Anyone know what this does? Is it related to the
self-reset situation?
Thanks for your help. 73,

Yep, sounds like an MFJ to me. the 1278 does that also. The periodic
blinking does not necessarily mean the modem has reset to ax25, sometimes
the 1278 just blinks, other times it goes into ax25 (standard) mode, other
times it gets hopelessly FUBAR'd.

Are there any known problems using a PK-88 with GRINOS (or any other
NOS variant)? I seem to have a good signal into the local switches,
but invariably I have problems making connections, etc after a few
minutes. I used to blame it on hidden transmitters, etc. but I'm
wondering if there may be other forces at work. AX25 connections appear
to work normally even while the IP stuff goes to heck.
Thanks for any info,

Hi Barry and everybody else at tcp-group
i have to reply from here as our internet access is
temporarily out of service. personal replies please to
stephan.walder @ alcatel.ch
These are the steps involved when I compiled WNOS5 for NETROM:
Step 1: compiled WNOS5 as it is (needed some adaption on the
assembler-flags (AFLAGS) in the makefile.
Step 2: enable NETROM and NRS in the config.h - file
Step 3: Correct the source-files
compiling this code now with make will fail on main.c.
In line 1149 a struct declared somewhere else is used:
nr4_cb. this part of the code is only active when
NETROM is switched on.
change nr4_cb to nr4cb !
2nd problem is in mailbox.c: the function mbox_incom
around line 182 needs the pointer *cp1 if NETROM is
enabled. i added the following lines to the declaration-
part of the function mbx_incom:
#ifdef NETROM
char *cp1
#endif
3rd problem: there seems to be another problem in
scc.c (pe1chl's driver). but as i didn't intend to
use that one for my tests i disabled SCC in config.h.
these 3 steps lead to a make-run with just the usual
few warnings.
with this wnos.exe i was able to establish tcp/ip-
connections via hb9zrh (local dual-speed-digi with
L2-digipeating off, so we had to go via netrom
for our link) to hb9ccq.
i can not yet tell which are reasonable settings for
all the parameters in wnos as we did not a lot of testing.
after ping, telnet and ftp went thru the weekend was over.
it seems to me that wnos whenever it gets a chance to send
(when polled from the dama-master) it is so happy it repeates
every packet 2 or 3 times...(also in normal ax.25 or netrom
connections). i haven't figured out yet where this behaviour
comes from.
i hope that help anyone trying to get wnos5 up and running.
BARRY
-----
it would be of great help if you'd send me the docs you
have on wnos5 via email ( to the address mentioned at the
beginning of this message !).
what you said on so many things to do and so few time:
the main problems seems to be spending abt 40h/week to earn
yourself a living...;-)
