Hello there,
i've got the folling problem.....
Kernel 2.0.29 + modules-12
module-utils-2.1.22b
tnos-2.21
tnc2/g3ruh:9k6 at /dev/ttyS0
dg1ees: 44.130.18.12 AND
dg1ees-svr:192.18.12.[1-254]
Tnos/Linux connected via ptypf/ttypf

IF i attach the tnc with tnos and Linux has got the 192# - i can acces the
radio from tnos and linux.

IF Linux kissattaches /dev/ttyS0 and Tnos hast got the 192# - than:

What does Protocol unreachable mean ? And what can i do to control the tnc
with kernel-ax25 and tnos runs via pseudolink with 192# ?
TIA, vy 73 de
