Mine will double the value of the \T register at random after reset. :-)

Mine weren't able to hold a V.32, trellis coding connection to several
T2500s and one Fury 9600TI (a german made modem which is said to hold
a V.32 connection even over rather noisy lines) for longer than a
minute (sometime less then 20 seconds on a local call).

I've been using this setting with the same result for 2 days. Seems to
work reliable.

At the moment I have the problem that that the stupid thingie insists
on loading \H1 even though I have set \H0 in both profiles thus
getting HP ENQ/ACK flow control. Anyone seen this problem?

I noticed also that the S23 register doesn't reflect the Baudrate and
Parity correctly. I tried 9600 and 19200 with no parity.

If I could get them to load the profile correctly i would be quite
pleased with them.

For what it's worth, ATI1 yields "173" and "V2.5" and ATI4 gives "SM96V+
V.42BIS" and "C-CODE".

My manuals do have an index and a table of contents, but the V.42bis
supplement is somewhat contradictionary to the normal manual.  I
wouldn't compare the handbook with the one for my T2500 but it isn't
really bad.
