Hi, Out of the questions with pskmail I have an other question! I am configuring a Rastberry Pi to be tested as a navcomputer. I have downloaded an compiled OpenCPN for Debian and everything works perfect exept that I can not get the usbport for the GPS/AIS to work. Knowing nothing about Linus/Debian this is a problem ;-) On a Ubuntu system that works directly. When selecting port for the device I have only ttyusb0 but I don´t get anything in. Is there a program that I can run to test the different ports? Anyone got any idea exept to read tfm? 73 de Gunnar
