Hi
I currently have been trying to get a RedHat 6 based system with a Kernel
2.2.17 upgrade working with a KISS TNC and it is all configured okay, but
for some reason after an initial connect, each time I send some plain text,
the packet appears to have another 2 characters appended to it after an
end-of-line, so if for instance I enter a command like 'B' to my local BBS
here, it appears at the other end to be something like 'UB' and is not
understood. The 'B' is still there, but the extra characters in the packet
cause it to have a frame problem.... the next few times you enter 'B', you
get a response for say 'UB', ':B','YB' and 'TB' or something afterwhich the
sequence repeats starting with 'UB'... To me it looks like the kernel is
sending out a checksum or something that it shouldn't, but I am not a C
source expert by any means - far from it.
Also if someone connects to me, axspawn runs here, but they get a frame
error sent back to them (probably with the extra characters!) and can't
login properly. I receive all packets okay.
An AXIP ping also seems to work once after a fresh restart of the system,
but will not generate a response afterwards. My 'listen' screen shows an ARP
received once from the other station, but then it just doesn't respond.
I don't know if there is enough information here, but does anyone recognise
this symptom?
I have kernel 2.2.17, libax25-0.0.7, ax25-tools-0.0.5, ax25-apps-0.0.4 on a
Pentium 100, with KISS on serial port compiled into the kernel (not a
module).
I also haven't got the OSS sound modules to load properly yet and don't seem
to find a kernel configuration entry for '/dev/dsp and /dev/audio' support
like there was in the 2.0.34/2.0.35 kernels. I have only ever had a 9600bps
soundcard based modem running on kernel 2.0.35 with a SoundBlasterPro card.
I am yet to try the new drivers (when the sound config works) and also the
NewQPSK mode.
Alot of interesting things in this newsgroup though... and for those in West
Australia, see you at the Hamfest on Oct 29.
