Reflection?? from WRQ software is a nice suite for Windows.
You can occasionally find it on e-bay for a decent price.
Depending on the version you find, it will emulate:
VT52, VT102, VT400, etc.
Newer versions include SCO-ANSI, ADDS VP2, Wyse 50+, Wyse 60,
DG215, Unisys T27, and AT386
I'm using "Version 10 for Unix and Digital" . . .?
It has a built-in visual basic scriping language, which is really cool.
I use that functionality daily. . . .
