From talking to several different people I get the feeling that doing serial interrupt handling with the PC might not be trivial. Even worse, I want to do it with DRI's version of C. The only mention they make of the serial ports is that they use special names for the console and printer (CON and LPT1). From this one is supposed to assume that the first port is COM1. Wll, so far that has not worked. Even if it did, it would not be interrupt driven, I assume. So, what I need is a solid set of assembly language routines for handling such things. I could probably develop something, but it would take a long time and would probably not be tight. If anyone could provide some assistance with this, I would be most appreciative, if necessary, financially so. Thanks in advance. -David Kovar ...decvax!dartvax!davidk

It has a routine (RS232INT.EXE or RS232INT.BAS) which run the port on an interrupt driven basis, and with a little work, can be interfaced with any C. I have an interface with PASCAL. The only trick is to get Version 1.0 of the program since it details what the entry points do. If you can not, I will be glad to help you with it. I recommend it since it will run and interface the PC to UNIX(tm) at speeds upto 9600 without dropping characters, which is the standard complaint that I have been hearing with people who are trying to interface with it a character at a time.
