I need info (and hopefully source code) for setting up an interrupt driver under Turbo Pascal 5.5 (or 6.0) to trap incoming characters from either COM1 or COM2. I know how to write the driver itself, and understand how to use TP to set it up as an interupt procedure. Wt I need to know are the values that the interrupt controller needs to get to "install" the driver as active. I have torn apart several manuals and ripped through pages of source code trying to "reverse engineer" this problem but I don't seem to be able to figure it out. Help or suggestions, please E-Mail.....thanx!

See the Dec/Jan 1991 (Vol 1 #5) issue of PC Techniques. There's also a book titled something like Programmers guide to serial communication. Good luck, John D. Mitchell johnm@cory.Berkeley.EDU
