Pascal,

The PI GPIO pins operate at 3.3 volts, and the PI is likely to
be damaged by applying 5 volts from a normal TTL port. You will need a level
converter on the TNC to PI lead. I used a simple resistor divider. Most TTL
inputs are happy with the lower voltage from the PI.
Normally the PI
linux kernel allocates the serial port as a console. You need to disable this to
use it for packet.
I've used the linux ax.25 and netrom code, and the linux node.
I haven't tried jnos.

Hello all,
I have a raspberry pi and I want to use it for making a packet
radio server. I have think to use jnos2 and I want to connect it with my
mfj-1270c tnc. This one have a ttl port on the back, can I connect it directly
to the GPIO port of the raspberry pi?
Other question, if I try to use a
usb to serial adaptor when I attach the port an arror says "protocol error",
don't know if it's because jnos don't like usb serial port. Any
clue?
Tnx
