Oops, that was written before the morning's coffee has soaked in. Peter's
point is (obviously) that he is using termcap info for the local terminal
(whatever it is) to translate between it and a remote VT100. The VT100
knowledge is hardcoded, but knowledge about the local terminal is table
driven.
Depending on the capabilities of the local terminal (e.g. scrolling
regions, 80/132-column switching, etc), a serviceable termlib-based vt100
emulator might be possible, to the extent it is useable by EMACS or vi, but
not necessarily by more demanding applications, such as those found on VMS.
