If you're running Ultrix, are you sure that this format in the L-devices
file is supported?  I definitly wasn't in older versions, and I don't recall
seeing it in any list of changes.  I've installed Ultrix 2.2 but am still
using the a copy of 1.2 uucp with lots of adb'd patches to make the internal
dialer support work with the trailblazers.

I'm pretty sure to make dynamic register settings you will have to code
the whole dialing sequence in the L.sys expect-send sequences.  It might
also be possible to use the acucap file, since some of the most blatent
bugs in the 1.2 version seem to have been addressed, see the comments
at the end file the acucap file.

This is the way it works.  Unless you set S50 dynamically based on the
type of call you wish to make, you're stuck with the S50=0 default setting,
which screws you if you either call a 2400 baud modem at 1200 baud or
call a trailblazer that has S92=1.

Here is a acucap entry that "worked" some of the time under Ultrix 1.2 -
It assumes you have a DMF32, which involves a lot of compromises.  You
might want to check out a couple of articles I posted to comp.unix.ultrix
about how the Ultrix acucap support works and problems therewith.  You
can get it to work based on that dope and a line monitor....
