Pick up a copy of FAS (Final Async Solution) at any fine FTP site near
you, and read the code.  Unlike the samples given in many books (eg:
SCO Device Driver Guide), this one actually works, _and_ has all the
bells and whistles.  In fact, you probably won't need to write your 
own -- FAS supports 16550 UARTS, AST (and clone) 4-port cards, and
has flow control that actually works.
