I'm sure this has been covered before, so please answer this by mail.
If requested, I will post the answers:

I want to set my SCO Xenix 2.2.1 (286) to go into cbreak mode, either
using curses, or directly using termio. However, the system drops DTR
whenever the setting ioctl() is called. A brief drop, but enough to make
our Trailblazer drop the line.

It has been suggested that I put a capacitor on the DTR line, so that
the (brief) DTR drop does not make it to the modem, but a longer drop at
the end of the call will effect the hangup. Still, isn't there a software
solution?
