I tried what you had but ran into a couple of problems.  First, when
trying to talk to the modem directly, I got what looked like a getty
war.  Sure enough, disabling getty before invoking cu fixed it; a bit
of head scratching and I guessed you're probably running your TB with
ATE0 as default.  That worked, but I don't understand why it's needed
for S53=4 but not for S53=0.

Unfortunately, even with ATE0, I ran into a babbling getty, this time
when uucico called a remote system and the remote sent out its login
prompt.  Couldn't figure out how to get around this one.

Also, where are all these hidden sub-fields documented?  I know of a
few of them, with the ",M" in Devices and "\M" and "\m" in Dialers
being the latest additions, but it's all come from word-of-mouth (or
is it word-of-fingers in this case?).
