I need to make a presentation about Unix soon.  To demonstrate, I plan to use
a Compaq Portable 386 running Xenix 2.3.3.  The Compaq normally displays on
an internal plasma but is capable of redirecting output to a standard CGA
port.  I would like to use that port to attach to an LCD overlay for an
overhead projector.

Under DOS, the key sequences Cntl/Alt/[<>] change the output between
the plasma and the port.  Under Xenix, I've been told that the commands

	vidi  cpq[01]

do the same thing.  But they don't work when I try them.  The "cpq" arguments
are not mentioned in my manual but they are present in the output of 'strings
/bin/vidi'.  Using the commands causes the plasma to wink, but output remains
where it was.

My vidi is:  -rwx--x--x   1 bin      bin        14744 Jun  1  1988 /bin/vidi
Is there a newer version?

Does anyone know where my problem might lie?  Any advice is appreciated.
