yes there is a section in xenix manual for writing a tty driver but it is 
only 500 lines. The SCO tech support claims that a true blue tty driver 
is about 2000 lines. We are missing 1500 lines ! What are they ? What does
that 1500 line is supposed to do ? That is exactly the problem. What are
the issues involved that have to be addressed in that 1500 lines ?
I guess except having access to a sample tty driver source code and running 
through it there is no way of writing a tty driver for a novice 
.
