I'm trying to get SCO Unix to communicate with a Windows 2003 Server via a RS232 serial cable. The software on the unix machine uses the wire link to communicate with Windows machine. There's a software on the windows server used to test the wire link but I keep getting a "hardware framing error". This normally suggests that the baud rates at the TX and RX are different, but they are indeed the same.
In trying to troubleshoot I would like to test if the windows machine is actually sending the correct info and also test if the unix machine is receiving correctly independent of the wire link. How would I go about doing this? The unix machine is receiving on COM2 (/dev/tty2a) and the windows is sending on COM6.
