I have a audio/video switcher (Sima VS-560) that accepts inputs via RS-232 serial port.

For example if I wish to look at a device that is sending and receiving data all the time from a computer - how could I Spy on that data to make it more useful to an end user Are there any methods in C/C++ VB to do this - if so how???

Data will be in the form of NMEA0183
