Well, I just received my program from VIEWDATA Inc. and it is *NOT* a vt100
terminal emulator, it is a NAPLPS terminal emulator.  Apparently, the VIEWTRON
system will work with a vt100, but works better (i.e. color, more facny graphics
and fonts, etc.) with NAPLPS.  Actually, the program also contains a crude
ascii terminal emulation (with control codes for up, down, left, right, and
clear) which could be used with a termcap were it not so botched up.  But the
NAPLPS mode (which is entered automatically when the  VIEWTRON host sends
certain escape sequences) is a different story and seems to work quite well.
Since VIEWTRON, once it puts you in NAPLPS mode, stays in that mode, the
package works quite well with VIEWTRON.  And with a full description of NAPLPS
protocol, one can probably write a termcap entry for it too (something I may
do in the future).  

So, a VT100 emulator it's not, but still a nice package for $2.50 (which incl-
udes a VIEWTRON user's guide and 1 hour on-line time).  VIEWTRON is somewhat
like an immature version of Compuserve.  On-line time is $.09/min non-prime,
$.22/min prime.  Same for 1200 baud.  The NAPLPS graphics are pretty thrifty
on transmission time; however, on the C64 at least, the hi-res screen paints
somewhat more slowly than conventional text at 1200 baud.

To whoever was looking for the vt100 emulator, quest onward.
