    Lemme guess, you tried to compile this using some new compiler on some new OS?
    Look at the dates - 1990 - that's old!!!!
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    you will not see anything on your computer's screen unless you attach something to the serial port that will echo (send) something to the serial port so that the program can capture and display it.

    It may only work with MS-DOS 6.X and earlier, or Win95/98. I double it will work at all on Windows 200 or XP.

    Capture from network interface instead of port

    You may want to capture from the protocol stack instead of directly from the port. You'll need a newer compiler though.
