Many thanks to those who responded. I haven't tried netfax yet,
but will summarize later if interests arise.
Here is what I've done to get it to work.
Configure the modem on the Sun w/ the following options (prefix w/ AT):
&Q5 Configured for V.42/V.42 bis operation
%C1 Enable MNP class 5 operation
\J0 Turn off DTE baud rate adjustment
Create an entry in /etc/ttytab:
ttyj0 "/usr/etc/getty new.19200" dialup on hardcar remote
I use a rotary table for testing of various speeds in /etc/gettytab:
n1200|new.1200|NDial-1200:\
:sp#1200:ht:ms=crtscts:nx=d2400:
...
n19200|new.19200|NDial-19200:\
:sp#19200:ht:ms=crtscts:nx=d38400:
n38400|new.38400|NDial-38400:\
:sp#38400:ht:ms=crtscts:nx=d1200:
kill -1 1 # to restart ttys
