CommLink Description

The COMMLINK application was desigend to be a small tool that connects two serial ports together so your computer can be used like an RS-232 data analyzer. It also allows one computer to use another computer's modem. COMMLINK can display all data on-screen as it happens, can log all captured data to a file, and can change both the logging and displaying on-the-fly. COMMLINK allows you to "mark" the log file with comments, and allows you to identify the ports you are using with descriptive names. Very important is that there be no IRQ conflicts between the two serial ports being used by COMMLINK! If the ports use the same IRQ, things will NOT work! If you can't use another IRQ for one of the ports, COMMLINK can be modified to work even with the IRQ conflict (if you have Visual Basic and can recompile COMMLINK). The only down side is that with an IRQ conflict, buffers are never used effectively, so characters will be dropped if speed exceeds 300 baud. To modify COMMLINK to work at low speeds with an IRQ conflict, find the TWO lines in POLLCOMM.BAS that begin: 'If EscapeCommFunction and remove the remarking apostrophe.
