Thanks go to Steve Bidwell for providing step by step instructions and
Steve Frazer and Celeste Stokely for supplying helpful URLs.

Here are the instruction suggested by Steve Bidwell:

These instructions were for a ZDX Multi Modem,
Solaris Dial-up with external modem ttya at 38400 baud
Unix Configuration
Enter run-level 1 with
init 0
At the OK> prompt type:
OK> setenv auto-boot? false
OK> reset
OK> set-defaults
OK> setenv output-device ttya
OK> setenv input-device ttya
OK> setenv ttya-mode 38400,8,n,1
OK> nvramrc
OK> reset

Connect the device to serial a port and set the handshaking to 38400,8,n,1
Remove port monitor on port a
pmadm -r -p zsmon -s ttya
edit /etc/ttydefs changing instances of 9600 with 38400 to read:

console:38400 hupcl opost onlcr:38400::console
edit /etc/saf/zsmon/_pmtab
substitute instances of 9600 with 38400 to read:

add a port monitor using a script:

pmadm -a -p zsmon -s ttya -i root -fu -v `ttyadm -V` -m "`ttyadm -Sn -d
/dev/term/a -b -m ldterm,ttcompat -l 38400 -s /usr/bin/login`" -y "38400"
force reading new port monitor settings:
sacadm -x -p zsmon

Modem Configuration
Connect direct to modem from PC using HyperTerminal on COM1
Issue these AT commands into the modem
