    Hannes, Even it it has TTL watch the levels - it is likely to be 5 volts, which would damage the pi input. A simple resistor divider can be used to drop it to

      Hannes,

      You will have to use a ttl to rs232 converter dongle unless you can access the Kantronis at the ttl level (the first way is simpler)

      Hi guys. Does anyone have some info on how to connect a raspberry pi to a kantronics modem using gpio serial port?

      Tnx
