Eric - this is the memo I did when I installaed my telebit. It may help
you avoid some pitfalls.

                           MEMO

Subject: TELEBIT MODEM SETUP

****  System paramaters and settings for modem. ****

The /etc/inittab line setup for 2400 baud (assuming use of tty33) should
be:

33:2:respawn:/usr/lib/uucp/uugetty -r -t 60 tty33 2400H # trailblazer modem
for 9600 baud, it would be:
33:2:respawn:/usr/lib/uucp/uugetty -r -t 60 tty33 9600H # trailblazer modem
for 19,200 baud it would be:
33:2:respawn:/usr/lib/uucp/uugetty -r -t 60 tty33 19200H # trailblazer modem

The ps -ft tty33 (at 2400 baud ) should look similar to:
 root 16349  1  0 20:44:00 tty33  0:01 /usr/lib/uucp/uugetty -r -t 60 tty33 24
and at 19,200 baud ...
 root 28981  1  0 11:13:03 tty33    0:01 /usr/lib/uucp/uugetty -r -t 60 tty33 19200H 

The /etc/gettydefs line should be:
2400H# B2400 # B2400 SANE IXANY TAB3 HUPCL #login: #1200H
and
19200H# B19200 # B19200 SANE IXANY TAB3 HUPCL #login: #9600H

[You can confirm the /etc/inittab, ps -ft and /etc/gettydefs entries
with the commands:

           grep 33: /etc/inittab
           ps -ft 33 
           grep 2400H# /etc/gettydefs 

The /usr/lib/uucp/Devices file must include these entries:

ACU tty33 - 19200 tbfast
ACU tty33 - 2400 tb2400
ACU tty33 - 1200 tb1200
ACU tty33 - 9600 tbfast
Direct tty33 - 19200  direct \D



The /usr/lib/uucp/Dialers file must include these entries:
tbfast =W-, "" A\pA\pA\pT OK \pATS51=254DT\p\D\r\c CONNECT\sFAST
tb2400 =W-, "" A\pA\pA\pT OK ATDT\D\r\c CONNECT\s2400 
tb1200 =W-, "" A\pA\pA\pT OK \pATS50=2DT\p\D\r\c CONNECT\s1200


****  Settings for the modem itself  ****

Reach the modem with the command: cu -l tty33 | tee (file_name)
Note, this will make a record of the standard out (screen) and in the 
file named (file_name), which you can then print.

When you get the indication, CONNNECTED, give the command at [return] 
until you receive the response, OK.  

To set the modem to run at fast speed using the UUCP g protocol, the
command line when CONNECTED to the modem is:

at &f s51=254 s52=2 s54=3 s110=1 s111=30 s45=0 q6 &w [return]

Then type atn? [return].  The current modem settings will print in the 
screen and also a copy is made in the file, file_name. The response 
should look like: 

at
OK
atn?

You can reset modem settings while CONNECTED to the modem with the command:
 ats0=1.  This command sets the contents of register 0 to 1.  See page 3-8 
of the manual.
