    Well you pretty much have to throw it away and read MSDN on how to use the serial port using the Win32 API.

    You can save all the code which deals with data once it's in memory.

    But all that serial port interrupt and hardware registers bit-bashing has to go.
    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.

    As Salem told you, this code is an old code for MS-DOS and won't work on WINDOWS!
