Rumor has it that Fred N. van Kempen may have mentioned these words:

VT52 is not a serial protocol. It is a (DEC) standard
for doing
screen and attribute control, akin to VT100, VT200, ANSI et al.
I know. Erm... maybe I mistyped unclearly-like. Lemme say it this way: The
screens in the Tandy 100/102/200 are serial. As such, it needed a way to
perform screen and attribute control. They used VT52 as the standard to
perform such control. So, anything that sends it VT52 codes down the RS232
into the TELCOM program are just shipped directly to the screen control
program, and they just work.
If that's still unclear, you'll have to wait 5 or 6 hours until it's time
(on my side of the planet, anyway...) to have a couple of beers at such
time my thinking processes will improve immensely. ;^>
One caveat: I _think_ the VT52 command set it has is only a subset of the
entire VT52 standard; how complete the subset is I don't know. If an
application needed support for a (possibly) unsupported VT52 command, it
may not function correctly.
But, yes, most DOS-based term programs (I use my own,
but Kermit,
Telix et al come to mind) did a good VT5x emulation, so using an
old lappy sounds smart!
So you see - I'm not as dumb as I look anyway! ;-)
