Hi,
I haven't solved my problem !! sorry I just need a small program which write a character ( or several) then read it from that serial port.
I used a null modem ( since I have just on serial port device).

I want a simple serial connection. I consulted Howto on tdlp and other ?? Now I can write on the port but not read !!

Thanks a lot
regards

What error message you got when tried read(2)? Did you use termios(3)?
