Trailblazer and non-BNU uucp

[Bill Mayhew]

The Trailblazer can work with non-BNU uucp.  If you get a device
not present error, make sure that the cable to the tty port carries
1, 2, 3, 4, 5, 6, 8 and 20 signal leads.  You may have to do an
initial set-up on an IBM PC before attaching the Trailblazer to the
Unix PC if the register settings are strange.  My recollection is
that pins 4 and 6 have to be high before getty and/or cu will
believe the device is really there.  You can aso do an "stty tty000
CLOCAL -HUPCL" on the line or set the termio(7) flags in
/etc/gettydefs to bring up the line without modem control to affect
the tests and adjustments to the modem.  You'll need to kill any
gettys and telinit Q if you edit gettydefs.  Editing gettydefs is
potentially dangerous, as you might ruin your ability to log in to
the machine if you bolux-up the file big time.  Also make a back-up
of gettydefs to restore the original conditions once the modem is
configured.

It is pretty easy to edit modemcap to support a TB modem.  You can
use the Hayes entry as a basis.  The key for success with the TB
modem is to allow enough time for PEP tone negotiation.  My tests
showed that calling anohter autobaud TB modem usually requires
about 45 seconds.  It is best to put the puause tokens in the chat
string in modemcap, rather than in the L.sys file, as it gets to
look pretty grody if you have umpteen /p tokens in L.sys.  You need
to add a line to L-devices and L.devices for the tty port where the
Trailblazer is attached.

I'll attach the modemcap lines I had for my Trailblazer for version
3.51.  It's been several years since I used them; as far as I know
the cpio archive I have of my old uucp was working.  There were
also bugs in the uucico distributed with 3.51.  Various people have
reported various degrees of bugs with it.  Most of the common
wisdom says that you never saw bugs if you used only tty00x or phx
for uucp, but not both the On Board Modem and external modem
intermixed.  I received updated uucicos from the AT&T hotline, but
none of them ever really cured the glitches which acted like the
vanishing clist buffers bug, but to a massive degree.  The BNU kit
does not seem to suffer from the problem.

One last note, make sure that you have S7 set to at least 60
seconds when calling into autobauding Trailblazers.

Note that if you use the User Agent to configure your set-up for
uucp, it will truncate any line in L.sys to a max of 80
characters!!!  Beware!
