I'm looking for C source (DeSmet C preferred) or 8088 assembler source
(IBM Macro preferred) for interrupt service routines for the COM1 serial
port on the IBM PC.  I have the IBM Async package with its RS232INT
driver, but no documentation on how it works internally.  My ultimate
goal is to write a high-speed input driver for a graphics tablet which
sends out coordinates along an rs232 line.  Any assistance would be
greatly appreciated.

  Thanks in advance,
