This posting is the configuration for Telebit's TrailBlazer modem under
HoneyDanBer UUCP. This is in response to many inquiries regarding various
setups for the TrailBlazer. Please send any questions or comments to:

SETUP INSTRUCTIONS FOR TELEBIT TRAILBLAZERS and HONEYDANBER (HDB) UUCP
The following HoneyDanBer examples should allow very easy initialization
of a TrailBlazer modem for use with HDB UUCP.
To begin with, edit the following entries into your Devices, Dialers and
Systems files:
Devices: (This may be copied almost literally. You fill in the correct port #'s)
ACU ttyxx - 1200 tb1200
ACU ttyxx - 2400 tb2400
ACU ttyxx - 9600 tbfast
ACU ttyxx - 19200 tbfast
Dialers: (This may be copied literally.)
tb1200 =W-, "" A\pA\pA\pT OK ATS50=2DT\T CONNECT\s1200
tb2400 =W-, "" A\pA\pA\pT OK ATS50=3DT\T CONNECT\s2400
tbfast =W-, "" A\pA\pA\pT OK ATS50=255DT\T CONNECT\sFAST
Systems: (Do not copy this literally. Fill in the appropriate info for your
application.)
hostname Any ACU 19200 phone# etc.
Your getty: Don't for get to set your getty up to include 19.2 in its cycle.
You may have it trying 19.2 first and moving to 2400 on the 1st
receipt of a break and to 1200 on the second receipt of break.
The order of the cycle is not important so long as the calling
system knows to send breaks until it sees the login sequence.
Next, the reset button on the back of the TrailBlazer Plus should
be depressed.
/***-> Depression of this reset button is not necessary if you are
just unpacking the modem for the first time. The effect of pushing the button
is to restore the Telebit Factory Defaults for the S register set. <-***/
Use a paperclip or some handy tool like that to depress the small
micro switch located (recessed) through a small hole next to the RS232
serial connector. Make sure the modem is powered on when depressing the switch.
Now with the modem in a known state open the modem's port at 9600 (using cu
or tip) and type the following string:
at &f s51=254 s52=2 s54=3 s110=1 s111=30 s45=0 q6 &w <CR>
This string, the spaces are unnecessary if you prefer to remove them, will:
1st (&f) recall factory defaults, (can't be too careful).
2nd (s51=254) sets up autobauding on the serial port (type the letter "a"
serveral times until you see it echoed).
--> Some versions of Telebit's documentation overlooked this value
for S51. It behaves exactly as the documented value 255 except
that a serial interface speed of 19200 is assumed on an incoming
call. (255 uses 9600 on an incoming call). <--
3rd (s52=2) says drop the connection when DTR is dropped to the modem and
reload the modem's stored EEPROM values, (do a soft reset).
4th (s54=3) says pass BREAKs through the modem transparently.
5th (s110=1) enables compression between TrailBlazers, (0 will disable).
6th (s111=30) enables UUCP "g" protocol support in the TrailBlazer.
7th (s45=0) disables remote access. When depressing the reset button s45 is
enabled to allow easier customer support. This is not the case when the
modem is originally shipped from the factory.
8th q6 silences the modem when an inbound call arrives. This prevents getty
battles between the RING result code and getty's echo of the same.
9th (&w) writes these new values into the EEPROM saving them as the modem's
power on defaults from now until you change them again.
AND
10th (<CR>) terminates the command to the modem.
You should now be able to run UUCP between two machines attached to your
modems just as you always have with slower modems. Enjoy the new world of
of high speed UUCP "g".
