        I've noticed that when using SCO XENIX 2.2.2 curses that calls to
refresh() say after a single character is to be placed on the screen (a great
example is your average 'talk' clone) that the cursor seems to home to the
beginning of the line, and then back to the position where the next character
is to be put; places the character, homes back to the beginning of the line,
and then goes to the position out there again.  This is at it's worse at baud
rates ranging between 2400 and 4800.  On BSD curses this doesn't happen (at
least not that I have seen.)

        Is there a way to overcome this in xenix curses?  A obscure mode
setting that I know nothing about?  Or am I doomed to having inefficient curses
routines.  I would think the former, since I am using the SCO word processor
right now (lyrix) and it is NOT doing this.
