Several mentioned using admintool which I have avoided. (Real Unix
weenies use command line)
Indeed I did follow the correct steps; the modem is screwed.

Michael Wangs answer:
1. fireup admintool
browse serial
double click port b
check expert
change template to "Modem - Bidirectional"
Port: b, service enable
Options: Bidirectional
Expert Options: Create utmp Entry
Baud Rate: 38400
Terminal Type tvi925
Login Prompt: ttyb login:
Comment: Modem - Bidirectional
Service Tag: ttyb
Port Monitor Tag: zsmon
Service: /usr/bin/login
Streams Modules: ldterm,ttcompat
Timeout (secs): Never
Click OK
2. On the back of US Robotics modem, flip every switch up except 3 and 8
3. tip -38400 /dev/cua/b
Connected
