An ISR is an Interrupt Service Routine, it's really quite a broad topic, and
essential
for good serial port communication:

I can't stress enough, that using SvaSync
http://www.delorie.com/djgpp/dl/contrib/svasync.zip
is a painless way to do serial port io.  If you still want to make your own you
will learn a lot from it.
