Well, one option would be to install minicom (apt-get will find it for you), set your default serial port to /dev/ttyS0, set it at 9600,7,e,1. Then plug it in and see if tapping W gets you a response. /dev/ttyS0 will look just like a file, if you're writing a program, and you can read from it and write to it just like any other file. -dsr- -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
