I'm working on a software development project that requires me to send signals to a device via RS232 port. Sadly the included utilities for transferring to and from the device would not work for mass distribution, so I'm left to writing my own. The included documentation doesn't really give any examples of the device's packet structure, and I would like to examine the packets sent to and from their included software package.
Does anyone know of a good program that would allow me to monitor packets coming to and from the serial port? Free is preferred, but not required.
