Summary: Here is what works for me


Hi,

Here is what works for me to control a Trailblazer on my 3b1.  I
have ver 4.0 firmware now, but the vax I talk to is still using
some level 3.x firmware, so I do not get the benefits of data
compression, etc that level 4.0 gets you.  None the less, I
typically get uucp throughputs of 850-950 char/sec on "short" files
under 40 Kbytes.  With longer files, I get "only" about 550
char/sec.

Note, you may want to add a couple of new entries to the attached
modemcap file to have an entry that initializes ATs95=0 for 1200
baud connections to computers endowed with non MNP modems (3b1's On
Board Modem, for example).  Unfortunately, it is the nature of MNP
to go brain dead when calling a plain-jane modem without MNP.  This
is not a bug in the Trailblazer, but rather a bug in MNP.  I have
seen the same thing happen with MNP on a US Robotics and on a
MIcrocom 9624.

I have included a couple of DIR entries in the attached L-devices
file so that you can use "cu -ltty000 -snnnn" to directly program
the Trailblazers S regiesters for those special occasions.  Since
L-devices is scanned top-down for an available device by uucico and
cu, you should probably stick with the ordering in my example.
Note to get 300 baud out of the On Board Modem, it seems to need a
different name than OBM for that rate-  I kind of liked "SOB" for
Slow OBm.  I didn't want to insult the Trailblazer by making it
have a 300 baud modemcap.

One thing I haven't implemented in modemcap is to search for return
strings like "BUSY" or "NO DIALTONE", and return with an error from
dialing.  That, as they say, is left as an exercise for the reader.
