Summary: I suspect CTS/DTR flow control has better response time.


I have never actually written a device driver that supported full DTR/CTS
flow control, but I would suspect that many feel as I did when writing
a driver for RT-11 (on a DL-11 controller) that DTR and CTS could be
handled at interupt time, while munging around for the tty structure and
then figuring out the tty modes would be too much hassle for an interupt
time routine.

Any thoughts?  Did I guess what you guys are thinking correctly?
