I suspect that it would be much easier to use the parallel port for what you want to do. I believe that you can directly drive the interface to generate an interrupt. Take a look at the book: The IBM personal computer from the inside out / Murray Sargent III and Richard L. Shoemaker. -- Rev. ed. -- Reading, Mass. : Addison-Wesley Pub. Co., c1986. for more information. Also, a nice piece of code to hack up for general hardware interrupt control (or use it as-is for serial interrupt control) under MicroSoft C is: PD1:<MSDOS.C>ASYNCPEC.ARC Interrupt-driven async comm rtns for MSC 5.x available from wmsr-simtel.army.mil (or mirrors/msdos/c/asyncpec.arc on wuarchive.wustl.edu).

I beleive the best way to drive serial port would be via a Fossil driver such as X00. One good thing about X00 is that it work... it always work, and it is very stable. Take a look at it. File is X00v1xx.zip where xx is the version number (current version is 1.24), and it's available on WUARCHIVE or SIMTEL Patrick Drolet big@info.polymtl.ca
