Is there a beginner-level document somewhere that tells how to
use the interrupts and interrupt functions in DOS?
I see lots of references to these...I suppose people use them to have
finer control over the hardware/system/bios than provided by the
functions usually provided by the compilers. Is this right?
Like for instance: I want to write a simple program to get/put chars to
COM1. Some compilers (like MIX PowerC) have a few builtin functions to
do this. I know, however, that there are interrupts (are these in bios
or dos?) that do the same.
Why would _I_ use one over the other? How would I know when which method
is appropriate? How would I do the int method?
thanx for your _Patience_ :-)
(Flames about compilers to /dev/null, unless you care to donate something)
