Greetings -

I would like to write a more efficient tty driver for my PC, an AT&T
6300 PLUS running SVR2.  The I/O board I am building will support 4 
ports and have a small buffer.  I have found several references 
to writing generic tty drivers that interrupt on each character, but
that is what I don't want to do. 

I am looking for furthur information regarding using polling, DMA, and
generally tweaking tty device drivers, as well as line discipline and 
modem control.  

I am aware of several products on the market that do this already, but
my objective is as much learning, as anything else.

Any help will be greatly appreciated.
