We have recently received Visual 603 graphics terminals at the terminal room
at OU, and they are the greatest thing since fire (relative to what we used
to have).  They have very nice graphics abilities, BUT they are only accessible
through "S".  I would very much like to access the graphics abilities myself,
but I cannot find any documentation for these terminals.  The only helpful
information I have been able to come up with is that they are supposed to
emulate a Tektronix (sp?) 4014.

Does anyone out there have a list of the graphics codes and what functions
they perform?  Alternatively, a low-level graphics driver in C would be great,
but I don't expect it.

Thanks in advance to anyone who will post or try to Email me with info or
ideas on where I can get the info.
