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!
