I'm trying to debug some old equipment and the serial comm protocols it uses. Years ago I used to have a program which ran on a separate computer in the serial link. The program displayed all the characters coming and going. I don't remember any more than that, but it was probably an MS-DOS program. Is there anything equivalent now, for Linux? Some way to pass /dev/ttyS0 straight through to /dev/ttyS1 and display the incoming and outgoing characters, perhaps? Thanks.<br>
