See your operating system software documentation for information about
other supported modems.
Modems must be configured such that the Force DSR attribute is not set.
(By clearing the Force DSR attribute, your system will recognize the loss
of modem connect, should this occur.) See your modem documentation for
specific information on clearing the Force DSR option.
When you order a modem, you may need to order a serial line cable and a
25-pin D-sub adapter to connect the modem to your system.
To connect your modem:
1. Set the ON/OFF power switches on both the modem and the system
unit to the OFF (0) position.
2. Follow the directions that come with your modem to set it up.
3. Use your modem guide to clear the Force DSR attribute on your modem.
(By clearing the Force DSR attribute, your system will recognize the
loss of modem connection, should this occur.)
4. Attach the 25-pin D-sub adapter to the back of the modem.
5. Attach one end of the serial line cable to the 25-pin D-sub adapter.
6. Attach the free end of the serial line cable to the modem port on the
back of the system unit (Figure C-5).
