If you do (you might have to be root) $ cat /dev/ttyS0 This will read your first serial port (ttyS1 for second port), and display what is at the com port. You might have to use stty to set you communication parameter such as baud rate etc, do man stty Your serial port is just a file to the os. So with some scripting (perl, python) you might be able to read something from a port, date stamp it and write it to a file. Just a thought . Andy R.
