Excuse me for answering this with IE 4.0 -- someone crashed my previous
Net-Tamer e-mail cache with a 250K file (shudder!)... and I had to retrieve
your message with a second pass on a different machine...

Yes, I've tried various connect speeds, and I was aware that 19,200 bps
should be about as high as I should go with an UART of 16450.

I see, but I was not referring to password authenticity; I meant that
I'm trying to combine appropriate hardware from the *time period* of
circa 1986 for this PC/XT -- I was making *aesthetic* considerations,
not technical ones. In other words, perhaps a 2400 bps ZOOM modem
is more appropriate for the technology of a PC/XT in 1986, than a
US Robotics Courier HST from 1989. That's all. Authentic hardware,
authentic peripherals. Would you know the approximate age of a ZOOM
2400 -- it's off white, about 12" x 8" x 1.5", with an on/off button in the
front right side? There's no information underneath it, and I don't have
a manual, so I'm lucky Dave Colston had an appropriate initialization
string for it.
As I've said, authentic hardware is more interesting to me at the moment
than high speed on this machine.
