Unix has a list of descriptions (usually called termcap or
terminfo) for many different types of terminals.  If you
tell vi that you are running a vt100, it uses the description
of a vt100 to control your terminal.

These terminal descriptions, unfortunately, are by no means
perfect.  Any system administrator (and anyone else with
appropriate permission) can go in and redefine what a
"vt100" is.

Thus, if PC-VT works fine, this only means that the vt100
terminal description matches what PC-VT expects.
It does not say anything about the ability of PC-VT to
really emulate the vt100.  The vt100 test program
referred to earlier was specifically designed to test
terminals and terminal emulators with respect to vt100
comnpatibility.  While it is surely not a complete test,
it does provide a better way of assessing vt100 compatibility
than using vi.
