First: The model number is not enough to identify the modems. There
are several versions. You also need the part number.
model part no. modem
1660 310476-01 Magic Modem TI-1660
1660 310476-06 Magic Modem 1660
1670 310476-02 U.S. Robotics
1670 310476-04 Commodore CR-1670
If you have something different, I would like to add the information to my
list.

If you have a friend nearby with a computer and modem, you can have
him/her set the modem to answer, and dial the number. With any simple
terminal program you should be able to communicate.

Just type in ATDT followed by the phone number, and press enter. It
should dial. This assumes touch-tone dialing, if not, use ATDP.

Not necessarily, you can blow the Carrier Detect gate without affecting
anything else.
Warning: on the 1660 used on a Plus/4, you must open the jumper on the
bottom near the connector, or you definitely will blow the Carrier Detect
gate.
