This link made it working but there some interesting stuff on linuxquestions to.
I got it working this way but I also wanted to get my gsm up and running. Searching for a solution to use my bt-mobile as a serial device. It’s in my wiki
I don’t know why but it keeps fascinating me. Maybe it’s just because I always forget how it works. I had a link to I/O Redirection on my blogger on blogspot but it was pretty hard to find it back so it’s more logical to put it here. Oh, btw, it’s all about bash io-redirection.
Sometimes there are links you always forget…
