Serial Mouse “Driver” / Tester

If you have a Microsoft-compatible serial mouse lying around and want to play around with it or test whether it works, this program I wrote in Borland C++Builder opens the serial port and actually reads information from the mouse. You can track the mouse’s position, and even patch the serial mouse into the Windows mouse driver (sort of). Give it a try. If you want, here’s the source code. There’s also a version for Visual Basic.
