To: tcp-group@ucsd.edu
Hello,
I use JNOS as an Internet gateway. I usually login into it
from 1200 baud radio side with ordinary AX25. My favorite
terminal program is SP5 (from DL1MEN) so my TNC works in
Host mode. I have found the following deadlock situation
during heavy traffic (it is very usual in Budapest, HA :-).
- JNOS repeating I frame for SP because it doesn't read
acknowledgement from SP.
- SP Rejects I frame from JNOS, but JNOS can not read it.
- JNOS repeating I frame for SP, but SP Rejects it only
ones. JNOS exhausts its repeat count and disconnects.
Host mode firmware repeats only twice the I frames, after
that it will send RR frames to test the other station. JNOS
repeats I frame all the time.
Have anybody met this situation?
73! de Andras.
