Back in the 90s a DOS program called Check-IT existed. Among others it 
had the capability of checking the operation of a serial or parallel 
port. You could even solder (buy?) a loopback connector which basically 
crosses lines so that anything sent to the port will loop back to the 
sending machine. That way automated tester application could test 
various RS-232 lines (RX/TX, CTS/RTS, DTR/DSR) and various baud rates 
for correct operation. At the time I actually could rule some of the 
tested ports being broken. However, most ports ever tested were ok and 
problems were somewhere else.
