  ReGIS compatibility on DECterm and VT340? 
 The Question is:
 
I have several applications which were written
to run on VT 340 terminals. Mostly they display
text as normal, reverse and bold with
positioning on the screen via escape sequences.
In addition, they use a certain number of ReGIS
commands to do some special "effects" on parts
of the screen. The applications have been in
production for a number of years and are well
tested and quite solid.
 
I would like to be able to run the applications
"as is" in DECterm's to get basically a windows
version of the system, essentially running
each application in its own window rather than
on a separate terminal.
 
When I try this, the text portions of the
display work fine. However, the ReGIS portions
not in the correct location and seem to be
shifted to the left a little. The VT 340 display
is 800 pixels wide and 480 pixels high. A little
experimentation with the DECterm seems to
indicate that it is almost 900 pixels wide, but
the ReGIS commands use just the leftmost 800
pixels although the display of a full 80
characters of text uses the entire width of
the DECterm (i.e. the character cell for a
single letter is more than 10 pixels wide).
 
This is a bloody nuisance. I would prefer not
to have to re-write the whole front end to use
Motif for the interface and go through the
whole development, debugging and testing
cycle to do something which would be very
simple if the DECterm truly emulated the VT 340.
 
Am I missing something obvious?
 
Does Compaq/Digital have any plans to fix the
DECterm?
 
Is there a third party or public domain program
which does the VT 340 emulation under
X windows correctly?
 
Thanks!
 
 
 The Answer is:
 
    Use the VWSVT fonts from the freeware CD.  The DECterm screen is sized
    based on the font in use.  The default font is not the same size and
    aspect as the VT200.  The VWSVT fonts have the exact size as the VT200,
    and the resulting DECterm window should work better.  No guarantees of
    off-by-one problems though.
