Actually, it's the other way around. The two working computers are laptops
and only have mic input. The troublesome computer is a desktop with both mic
and line inputs. I've tried both on that system with no sucess. Thanks for
the info about the possibility of overload though.

KPC 9612+ and kissattach

Hello All,
  I have searched the archives, but cannot find a solution to my problem.

2 machines trying to talk to each other.  One seems to work, one doesn't.

Software config the same on each one - RedHat 7.3 with the ax25 libs and
utils installed.  Kernel recompiled to support ax25 and kiss devices.

The machine that works is using a Kenwood D7A radio at 9600 baud in kiss
mode.  kissattach seems to work, and if I ping the other end of the radio
link, I get the radio going in to transmit mode in sync with the ping
packets.

The other end, however is a different story.  It's a Kantronics KPC 9612+,
with no radio on the first port, and a 9600 baud radio on the second port.
Minicom works fine, and I can connect to the tnc and send and receive data
on the TNC.  My problem appears to be with mkiss.  Am I correct in assuming
that I need to run mkiss because the KPC 9612 is a dual-port TNC?  I am
running the foillowing commands:

mkiss -s 9600 /dev/ttyS0 /dev/ptyq0 /dev/ptyq1
kissattach /dev/ttyq1 RADIO 172.16.0.2

The commands are accepted, and a network device is create, but if I ping, I
get no radio traffic at all.

I am suspecting that I need to do something fancy before I go in to kiss
mode on the TNC.  At the moment, I'm just doing a mycall followed by intface
kiss.  Should I do something else?

Check the AX25-HOWTO section 6.1.1.1 ("Configuring for Dual Port TNC's")

Re: KPC 9612+ and kissattach

Thanks for the quick response.  I did consult the HOWTO, and my commands are
based on the ones you listed.  I'm only using the 9600 baud port, so I only
have a kissattach line for the second port.  This is not working, however.
What I wanted to confirm is that I'm correctly putting the 9612+ into kiss
mode.  I'm using a factory default config, with MYCALL set, and then INTFACE
KISS.  Is this correct?  All of my configs work just fine connecting to the
TNC in a Kenwood D7A handheld, but not the KPC9612.

Thanks.

ftp.torun.ampr.pl   /pub/linux/minilinux/

Use a FTP client, some web browsers (IE) may have a problem accessing 
the site.

Try configuring both ports and see if it makes any difference.

I seem to recall that I had to set 'ABAUD 9600' to force the TNC to use 
9600 Baud for the serial port instead of it's default auto-detect method. 

Are you sure 'INTFACE KISS' was accepted ? (The TNC may not let you go
from NEWUSER mode to KISS directly, you might have to do 'INTFACE 
TERMINAL' first).
