Help! I am having difficulties setting up a Telebit Trailblazer plus to a
Sun 4/260 running Solaris 2.2 .
I've set up the modem on serial port "b", and I've created the following
entry in my "/etc/remote" file:
cuab:dv=/dev/cua/b:br#9600:pn<phone number here>:hd:
The cable I'm using is:
1 - 1
2 - 2
3 - 3
4 - 4
5 - 5
6 - 6
7 - 7
8 - 8
20 - 20
I believe "tip" is making connection to the device 'cause the dtr light
on the modem comes on when I issue the command "tip cuab", but then I
get stuck.
How do I get tip to work to establish a connection?

Thanks got out to the following people, some of whom actually responded
on a Saturday!

and to those who might respomd later.
The document I used to get things going came from Kevin Cosgrove and I have
included it below:

> Dial-In configuration:
> ----------------------
> The dial-in configuration uses a "fixed speed" getty, and the modem is

> 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).
