COURIER HIGH SPEED MODEMS
nector, while the port on the IBM PC/ AT and some compatibles
requires a DB-95 connector. Apple computers require a DB-25P,
DB-9P or, more typically, an 8-pin round plug connector. Check
your computer documentation or with your computer dealer.
NOTE: Appendix B includes a listing of RS-232 pin assignments
required to operate the modem. Be sure to check the appendix if
you're not sure what type of cable you need, or if you're building
your own. If your machine has other than a 25- or 9-pin port,
check your computer documentation or consult your dealer to
find out what type of RS-232 connector is required.
WARNING: If you're planning to use the high speed computer-
to-modem rates of 57.6K or 38.4K bps, follow the instructions
concerning the RS-232 cable in Appendix B. The guidelines
there will help you to avoid signal degradation at very high
speeds.
SWITCHES
Voice/Data
This pushbutton switch is used primarily to switch between
voice and data communications during a call. Detailed
instructions are in Appendix E, Voice/Data Calls. The switch has
multiple functions, however. Options are as follows:
Disable the switch
Force the modem off hook in Originate mode (default)
Force the modem off hook in Answer mode
Have the modem redial the last dialed number
Have the modern dial the first number you've stored in
nonvolatile memory
Toggle Auto Answer on and off
Reset the modem to its defaults
Initiate Remote Digital Loopback testing
Busy out the phone line
Volume Control
This is a slide switch underneath the right side panel of the
modem, near the front corner. Sliding it toward the front of the
modem increases the volume of the modem's speaker; sliding it
toward the rear of the modern decreases the volume.
