[comp.sys.dec] Rainbow VT240

Gentlebeings:

  I am currently enmeshed in a Software Design course, in which a five-member
team has to implement a software system under VMS (currently we have v4.6),
and which must be demonstrated to our professor (his "acceptance test") on
a Rainbow running what's rather loosely called "the VT240 emulation" soft-
ware.  The problem is that, after testing the emulation package, it turns out
NOT to be a "true" VT240 - more like a "half"-VT240.  I.e. it supports ReGIS
screen display, Sixel-mode screen-dump-to-printer, but apparently NOT Sixel-
mode screen graphics, down-line-loadable character sets, or most of the other
emulation modes which the true VT240 can perform.  

  Worst of all, though, this beast's "identify terminal" response to the 
SET TERM/INQUIRE (identify terminal) command of VMS, MIS-IDENTIFIES ITSELF as
having Sixel graphics, etc., which it DOES NOT have; therefore, there is NO
way for our software on VMS to know whether it has available a true VT240 or
this impostor.

  My query: does anyone have either a "better" VT240 package for the Rainbow,
OR documentation for the "REGIS240" software (and/or the board required to
use it) in conjuntion with the "TRM" terminal program, OR some sort of work-
around that we can use on VMS to differentiate between the Rainbow-running-
fake-VT240, and the REAL VT240 ?

  Replies via E-mail, please, as this is going to three different newsgroups.
Thanks in advance.
