Pseudotty and /dev/tty

[Larry W. Virden]

A friend is working on a small program that attaches a pseudotty and then
runs programs against it (programs like vi, etc).  He has the most of the
pgm working, but finds that when a program opens /dev/tty, it doesnt get
and error, but the output doesnt appear to the user either.

What types of things must one be aware of when setting up this type
of situation.  The program is currently running under ultrix 2.3, with a port
to SunOS 4.0.1 in the future.
`
Also, is there some good, non-proprietary source or doc that one could read 
about to show who to do this type of thing?  Thanks
