Also, once the interrupt occurs, what vector does it jump through? I *think* I know how to get it to generate the interrupt -- what I don't understand is how to tell it where to okgo once an interrupt is generated. I'm using Microsoft C 5.1, and sample code in that dialect of the language would help tremendously. I also have access to Turbo C (don't know the version), so sample code could work for that also. References to books would also help, unless they are to books on assembler -- I'm not familiar with 80xxx family assembly language, so I would have to go through a complete learning curve just to understand what you had referred me to. Basically, I'll take any help I can get. My object is to write a rudimentary serial communications library in C which closely mimics the behavior of C's standard stream i/o functions. Any pointers? Finally, I have a very difficult time keeping up with this newsgroup as I don't get a chance to log in daily. So, could replies please be sent via e-mail? I promise/swear/sign-in-blood that I will summarize to the net if response is high enough. Thank you for your time (and knowledge) -- Thanks Chris Cleeland, Tulane University ADDRESS: cleeland@rex.tulane.cs.edu Disclaimer: "I'm a student -- I can't afford to buy one!"
