Yes. It's fortunate that all the possible settings are listed
cleanly underneath the US Robotics Courier, but that's where it
ends. The factory setting is AT&F, but it doesn't help.

The UART on this PC/XT is 16450, which *should* allow for at least
a 14.4 connect (I know of others who do on XTs quite successfully).
This Robotics modem indicates V.32, and so I used Dave's string:
ATZ^M AT&S7=58X6&B1&H1&R2&C1&D2&S1
The ZOOM 2400 string, which works like a charm, is:
ATZ^M AT&C1&D2&K3&S1
This ZOOM string hasn't failed yet -- but the "fancy" Robotics
modem appears helpless.
Oh well. My main concern is approximate "authenticity" of hardware
for this PC/XT from 1986. The Robotics modem is dated 1989; the ZOOM,
I don't know (would anyone venture a guess at its age?) -- so my
only benefit would be speed with the Robotics, and probably less
authenticity than that of the ZOOM.

Well, I think in the case of this XT, I should strive for
authenticity, not productivity. Nonetheless, if you have any
further suggestions, I think I won't risk creating an hysterical
ruckus at the ISP office over this "dinosaur"... ;-)

I'd be surprised if the line is "dirty", because I've had it checked
and corrected a few years ago and always get 50k plus connections
with my V.90 modems on other machines with this same line...
Thank you!
