Well, below I've included "Celeste's Guide to Terminals & Modems in Solaris 2.x"
which should be quite helpful.

This document uses a "cook book" approach to setting up modems and
terminals under Sun's Solaris 2.x. It is not a tutorial and does not
cover all variations of serial port usage. But, between the explanations
and the scripts, you should be able to get common asynchronous modems
and terminals working fairly quickly.
You must execute the commands as root and you will probably have to
reboot the machine. So, plan the system's downtime accordingly.
You may distribute this information to anyone who wants it, as long as
you never attempt to copyright it in any way. If you find errors in it,
or have suggestions for changes in future revisions, please let me know
via email. Go for it--you can do it!

A. Setting up a terminal on Solaris 2.x
=======================================
*********************************************************************
*** IMPORTANT NOTES: ***
*** 1. All single quotes in these directions are BACK QUOTES, ***
*** not FORWARD QUOTES, except where specifically noted. ***
*** ***
*** 2. Be sure and execute these commands as root, from a ***
*** BOURNE shell (sh), not ksh, tcsh, or csh. (If you put the ***
*** commands into a Bourne shell script, that's fine, too.) ***
*** ***
*** 3. If, after following these instructions, you get ***
*** terminal failures, and you're not using a script, then ***
*** make sure that root's default shell is /sbin/sh and not ***
*** csh. ***
*********************************************************************
BEFORE YOU BEGIN: SETTING UP THE TERMINAL
- Set the terminal for the speed you wish (example below
assumes you are using 9600 baud)
- The only lines you really need in the terminal-to-Sun cable
are 2, 3, and 7. Be sure to cross lines 2 and 3 in your cable.
- Set the terminal for Xon/Xoff flow control
- Set the terminal for 7 bits, Even Parity. (1 stop bit, if
you have that setting.) If you want a different parity or
word length, see Section D of this document.
ENABLING SOLARIS FOR A TERMINAL:
- Save the following script as add_terminal
- make it executable with "chmod u+x add_terminal"
- Edit add_terminal to meet your particular needs
- Execute add_terminal
- If the terminal doesn't give you a login when you hit <return>
try rebooting the machine once.

B. Setting Up a Bidirectional Modem on Solaris 2.x
==================================================
BEFORE YOU BEGIN: SETTING UP THE MODEM
Be sure that the modem is configured in the following way:
- Hardware DTR. When the Sun drops DTR the modem should hang up and
reset the modem.
- Hardware Carrier Detect. The modem only raises the CD line when
there is an active carrier signal on the phone connection. When carrier
drops, either when the other end of the connection terminated or if
the phone connection is broken, the Sun will be notified and
act appropriately. The CD signal is also used for coordinating dial-in
and dial-out use on a single serial port and modem.
- Respond with numeric result codes. (Usually this is ATV0)
- Sends BASIC result codes ONLY. (Sometimes this is ATX0 or ATQ0)
- Does not echo commands. (Usually this is ATE0)
- Modem is locked at a single speed setting between Sun and modem.
Speed may vary as needed between local and remote modem, but
should remain constant between Sun and modem.
