raspberry pi for packet radio

ve2hom <ve2hom@...>

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?
