This is the lastest setup document straight from Telebit:
Dan,
That is the latest setup guide we have available for setting up Telebit
modems on a SUN SPARC, and thanks for the positive feedback on the
setup guide. I thought I would append the guide to this E-Mail just in
case you need a backup copy.

Telebit/SunOS 4.1.x Setup - Revision 2.02 - 5 MARCH 1993 - Page 1 of 5
============================================================================
SETUP INSTRUCTIONS FOR TELEBIT MODEMS AND SUN WORKSTATIONS WITH SUNOS 4.1.x
The following examples should allow easy initialization of a TELEBIT modem
on a Sun workstation running SunOS 4.1.x. This guide describes the steps
for installing any Telebit modem except for the QBlazer transportable modem.
QBlazer installations are described in another guide.
Most installations use the modem for both dial-in and dial-out, so this
guide describes how to configure the computer and modem for combined dial-in
and dial-out operation. If you're not going to use the modem for both types
of operations, skip the section that doesn't apply to your installation.
These examples assume the modem will be attached to the computer's "ttya",
port, which is one of the on-board ports in most Sun workstations. If the
modem is on a different port, substitute the other port name in your setup.
Although the WorldBlazer, T3000, and T1600 modems can support RS232 port
speeds higher than 19200 bps, this guide configures them for 19200 bps on
dial-in. 38400 bps operation may not be reliable on some workstations or
serial port boards, so it's wise to start with the slower speed first.
Later, when you're sure everything else works, you can try boosting the
speed up to 38400 bps.
---[ Section 1 - Pre-Installation ]-----------------------------------------
Before performing any other installation steps, the computer and modem need
to be prepared for each other.
1.1 Turn off any getty processes that might be running on the modem port by
editing the /etc/ttytab file and re-starting init.
Edit the /etc/ttytab file with a text editor. Find the entry for the
modem port and change that entry's status field to "off". It should
look like this:
# name getty type status comments
#
ttya "/usr/etc/getty std.9600" unknown off local secure
Save the changes and exit the editor.
Enter this command:
kill -HUP 1
1.2 Reset the modem to its factory default settings as documented in the
Reference Manual or User's Guide.
WorldBlazer/T3000/T1600 modems: Reset modem to TTY defaults (&F0).
T2500/TrailBlazer Plus/T2000/T1000 modems: Reset modem to Enhanced
Command Mode (ECM) Asynchronous defaults.
1.3 Connect the modem to the computer through the RS232 serial cable,
and plug the telephone line into the modem's LINE jack.

============================================================================
---[ Section 2 - Modem Configuration ]--------------------------------------
2.1 Change directories to /dev and enter the following command to create
the dial-out device file for the ttya port:
mknod cua0 c 12 128 (for ttyb enter: mknod cub0 c 12 129)
If the mknod command returns a "file exists" error, skip to Step 2.2.
Otherwise, enter the following command:
chmod 666 cua0 (for ttyb enter: chmod 666 cub0)
2.2 Change directories to /etc and edit the /etc/remote file with a
text editor. Create the following entries:
tb38400:dv=/dev/cua0:br#38400:el=^C^S^Q^U^D:ie=%$:oe=^D:
tb19200:dv=/dev/cua0:br#19200:el=^C^S^Q^U^D:ie=%$:oe=^D:
tb9600:dv=/dev/cua0:br#9600:el=^C^S^Q^U^D:ie=%$:oe=^D:
Save the changes and exit the editor.
2.3 Enter this command to connect to the modem:
tip tb9600
NOTE: If tipping through the SUN Open Windows environment, use a SHELL
tool, *not* a COMMAND tool.
2.4 Type the following commands to the modem. Use only the commands
for your particular modem:
WorldBlazer, T3000, or T1600 modem:
AT &F3 E1 X0 &S0 S2=255 S45=255 S48=0 S58=2 &W
AT S59=15 S68=255 S111=255 S180=2 &C1 &W
T2500, TrailBlazer Plus, T2000 or T1000 modem:
AT &F X0 Q4 S45=255 S48=1 S51=254 S52=2 S54=3 &W
AT S58=2 S64=1 S66=1 S95=2 S97=1 S106=1 S131=1 &W
When you press Return at the end of a command, the modem should
respond with "OK". If you get disconnected on the first command,
repeat steps 2.3 and 2.4. You can review the modem's settings by
typing "AT&V" or "ATN?".
Exit tip by pressing Return, Tilde (~), and then Period (.).
----------------------------------------------------------------------------
NOTE: Check your modem reference manual for descriptions of each
register and the meanings for each of the above settings.
In the TrailBlazer Plus, T2500, T2000 and T1000 settings, the
S97 and S106 registers control V.42/LAP-M error correction.
If your modem doesn't have V.42 support, you can omit S97 and
S106 from the modem commands. The S131 register controls the
modem's DCD signal. Older modems used the S53 register to
control DCD instead of S131. If your modem doesn't support
S131, then set S53=1 instead.

============================================================================
---[ Section 3 - Setup for Dial-Out Operation ]-----------------------------
3.1 Edit the /etc/remote file with a text editor and add the following
entry:
TELEBIT|Telebit autodialing parameters:\
:el=^D^U^C^S^Q^O^@:du:at=hayes:ie=#$%:oe=^D:\
:dv=/dev/cua0:
Save the changes and exit the editor.
The entry above describes to tip how to talk to the Telebit modem.
You can add entries for dialing other computers and have them
reference the Telebit info using the "tc" parameter. For example:
home|call my computer at home:\
:pn=5551212:br#19200:tc=TELEBIT:
3.2 Change directories to /etc/uucp and edit the Dialers file with a
text editor. Create the following lines:
# tbnorm: for 'normal' calls with modem error control
# tbplain: for 'plain' calls without error control
# tbuumnp: for selecting UUCP protocol support in MNP mode
# tbuupep: for selecting UUCP protocol support in PEP mode
tbnorm =W-, "" ATE0X1 OK ATDT\T CONNECT
tbplain =W-, "" ATE0X1S180=0S95=0S97=0S106=0 "" \dATDT\T CONNECT
tbuumnp =W-, "" ATE0X1S111=30S180=3 OK ATDT\T CONNECT
tbuupep =W-, "" ATE0X1S7=60S50=255S111=30 OK ATDT\T CONNECT-\c-CONNECT
Save the changes and exit the editor.
3.3 Edit the Devices file with a text editor. If there are any lines
that reference the modem dial-in port (ttya) or dial-out port (cua0),
comment them out by inserting a "#" at the beginning of each line.
If you have a WorldBlazer, T3000, or T1600, create these entries:
ACUNORM cua0 - 300-38400 tbnorm
ACUPLAIN cua0 - 300-38400 tbplain
ACUUMNP cua0 - 300-38400 tbuumnp
If you have a WorldBlazer, also add this entry:
ACUUPEP cua0 - 300-38400 tbuupep
If you have a T2500, TrailBlazer Plus, T2000 or T1000 create
these entries instead of the ones above:
ACUNORM cua0 - 300-19200 tbnorm
ACUPLAIN cua0 - 300-19200 tbplain
ACUUPEP cua0 - 300-19200 tbuupep
Note the highest RS232 port speed for these modems is 19200.
Save the changes and exit the editor.

============================================================================
---[ Section 4 - Setup for Dial-In Operation ]------------------------------
4.1 Change directories to /etc and edit the gettytab file with a text
editor. Look for the entry named "std.19200". Modify the entry
to match the following example. If the entry doesn't exist, create
it as a new entry:
std.19200|19200-baud:\
:sp#19200:ms=crtscts:
Save the changes and exit the editor.
4.2 If the modem is not connected to one of the on-board serial ports
(ttya or ttyb), then skip this step. Go to Step 4.3.
Before getty is started, the computer must have its "software" carrier
detection disabled. Without software carrier detection the computer
will respond to the modem's DCD signal. This is critical for correct
operation with a modem. The computer must respond to DCD. Enter the
following command:
ttysoftcar -n ttya
You can confirm the kernel's handling of the modem port by entering:
ttysoftcar ttya
The system should report "ttya is n".
4.3 Edit the ttytab file with a text editor. If there are any lines
that reference the dial-out port (cua0), delete them. The system
must NOT run getty on the dial-out port device. Getty should only
be run on the dial-in port device (ttya). Modify the dial-in port
line to look like this:
ttya "/usr/etc/getty std.19200" dialup on
You may add other status keywords after the "on" keyword, but be
sure you do NOT add the "local" keyword. "Local" defeats the
hardware carrier detect configuration we did in Step 4.2. If you
are installing the modem on a multiport board, follow the setup
instructions for your multiport board to create the ttytab entry.
Save the changes and exit the editor.
4.4 Start getty running on the dial-in port by entering this command:
kill -HUP 1

---[ Section 5 - Configuration Notes ]--------------------------------------
Some users turn the speaker off (M0) and disable remote access (S45=0) when
the modem installation is finished and everything is working properly.
Dial-In configuration:
----------------------
The dial-in configuration uses a "fixed speed" getty, and the modem is
configured to always communicate with the computer at 19200 bps. Even if
someone calls in at a different speed (e.g. 2400 bps), the modem will
manage the difference in speeds.
The modem is configured to use RTS/CTS flow control, also known as "hardware
handshaking". The computer must also use RTS/CTS flow control, or data
could be lost in some situations. The "ms=crtscts" code in gettytab turns
on the computer's RTS/CTS flow control, however this code may not work on
all Sun workstations. Multiport boards may use other methods for enabling
RTS/CTS flow control on the computer's serial port. Contact your Sun
support group for more information on whether your computer can support
RTS/CTS flow control. If your computer cannot handle RTS/CTS flow control,
configure the modem for 'compromise' XON/XOFF flow control (S58=0 S68=3) in
Step 2.4, and remove the "ms=crtscts" code in the /etc/gettytab entry.
If you want your dial-in configuration to use a different port speed (for
example, 9600 bps), adjust the modem's S51 register accordingly and use the
correct speed entry in /etc/gettytab.
Dial-Out Configuration:
-----------------------
Tip's dial-out configuration is controlled by the /etc/remote file. Check
the man page for tip and remote, or contact your Sun support group if you
need more information about configuring tip (e.g. turning on RTS/CTS flow
control). The uucp dial-out configuration supports port speeds from 300 bps
to 38400 bps for the WorldBlazer/T3000/T1600 modem family, and speeds from
300 bps to 19200 bps for the T2500/TrailBlazer Plus/T2000/T1000 modem family
(see note above). The dial-out scripts in the Dialers file are used to
configure the modem for the most common types of calls. Note that the
"tbplain" script takes advantage of certain capabilities among the older and
newer families of Telebit modems, where the modems can accept commands
intended for the other modem family.
Example Systems file entries to access the different dialers:
mysystem Any ACUNORM 19200 5551212 ogin: hello ssword: itsme
mysystem Any ACUPLAIN 19200 5551212 ogin: hello ssword: itsme
mysystem Any ACUUPEP 19200 5551212 ogin: hello ssword: itsme
mysystem Any ACUUMNP 19200 5551212 ogin: hello ssword: itsme
The third field in each Systems file entry declares the 'device type'
to be used for the call. This field is matched to the first field in
the Devices file entry to select the dialer. The different device types
in these examples will select the appropriate features in the modem.
NOTE: The "ACUPEP" device type is not appropriate for T3000 or T1600
modems (they don't support PEP). The "ACUMNP" device type is
not appropriate for the T2500/TrailBlazer Plus/T2000/T1000 family
of modems (they don't have UUCP protocol support in MNP modes).
