Tip
and /etc/remote You may hate tip and love kermit or pcomm. I understand. But, do this via tip to keep it simple, ok?
Decide which serial port you want to use. (One with no cable already plugged in is often a good bet.) The port will be labeled "A", "B", "A/B" or could even be "C" or higher.
If you use one labeled "A/B" and have no Y-type splitter cable plugged into it, you'll have access only to port A. With the splitter, you'll get ports A and B on separate sockets of the splitter cable.
The Sun serial port device driver splits each physical port into two logical
devices, /dev/term/a or /dev/term/b for incoming transmission, and
/dev/cua/a or /dev/cua/b for outgoing transmission.
The speed referred to in this section is the DTE or Sun-to-modem speed. It is NOT the modem-to-modem speed. A 14400bps modem may have a 19200bps DTE speed.
Make sure you have your serial port permissions right. uucp should own the
outgoing side, and root should own the incoming side.
Execute these commands as root, substituting your port name (a, b, c, or d) where needed:
prompt# chown uucp /dev/cua/a; chgrp tty /dev/cua/a prompt# chown root /dev/term/a; chgrp tty /dev/term/a
/etc/remote, and find the entry beginning
with "hardwire:". This is the entry you use to program the modem, and is
not usually used for dialing out directly, unless you enjoy AT commands.
(If this is the second modem you're adding, clone the entire hardwire
entry and label the new entry "hardwire2".)
Change it from an entry like:
hardwire:\
:dv=/dev/????/?:br#????:el=^C^S^Q^U^D:ie=%$:oe=^D:
to one set to your port (like /dev/cua/a) and baud rate (like 9600):
hardwire:\
:dv=/dev/cua/a:br#9600:el=^C^S^Q^U^D:ie=%$:oe=^D:
Now use your edited "hardwire" entry from /etc/remote and type:
prompt# tip hardwire (or "tip hardwire2")
you should see "connected"
type:
ATE1V1<carriage return>
(This will work for all Hayes-compatible modems, even cheapies.)
Now, issue the appropriate AT commands to program the modem. (See the section called Basic Modem Programming. Don't forget to write the new settings out to the modem's NonVolatile RAM.
/etc/remote, verify the modem cable.
<carriage return>~. (This means to type 3 separate keys, one at a time, of <carriage return> <tilde> <period> This will also exit rlogin, so if you're running tip through an rlogin, make that <carriage return>~~. (<carriage return> <tilde> <tilde> <period>) or you'll only exit rlogin.)
/dev/cua/a. Convoluted, eh?)

number 14155551234 via a 19200bps 7 bits, no parity connection on

Putting this in a script is a Very Good Idea because if you make a mistake, you can easily fix the problem and rerun the script. Don't try to do this without a script--there are too many typing errors waiting to be made in these commands.
Type in the following script as a file (for instance, /sbin/add_modem), make it executable, then run it.

Enabling Solaris For A Dial-out-only Modem
If there is no port monitor running on the port, then the Sun will not try to spawn a login. So, you have to remove any port monitor on the port. There is much disagreement over whether these eeprom settings are required. Just use them and it will work.
