Connecting the PC Modem to a PC
To connect the PC modem to a PC, do the following:
1. If the terminal-emulation program has not been installed on the PC, install it using
the program manufacturer’s instructions.
2. Connect one end of a 9-pin-female-to-25-pin-male cable, or a 25-pin-female-to-
25-pin-male cable, to the serial port on the back of the PC. Connect the other end of
the cable to the connector on the back of the modem.
3. Turn on the power to the PC and start the terminal-emulation program. Configure the
program for the appropriate serial port and baud rate, using the program
manufacturer’s instructions.
4. From the PC keyboard, type AT, and press the Return key. Depending on the current
modem configuration, either OK or 0 appears on the screen. If either of these
appears, skip to step 7.
5. If nothing appears on the screen after you have pressed Return, watch the RD
(receive data) and the SD (send data) LEDs on the front of the modem as you type
ATE1. The RD and the SD LEDs should light as you enter the command. The
modem is now configured to echo the keyboard command. If the LEDs light as the
command is typed, skip to step 7.
6. If the RD and SD LEDs do not light as you type the command, make sure that the
cabling between the modem and PC is correct. If the modem still does not respond,
make sure that the PC parameters are correctly configured, such as serial-port
configuration and the serial-port number in the communications software.
The modem connected to the remote PC can retain the factory default settings or it
can be set to the user’s normal configuration.
7. Change the modem settings, as required. On the PC keyboard, type AT&F&Y0&W0
and press Return to recall the factory defaults and write them to profile 0. Use these
settings when the modem is powered up. The only setting suggested other than the
default settings for the Boca 14.4Kbps V.32bis modem is to type the ATE1&WO
command and press Return to enable character echo.
8. Type AT&V and press Return to view the modem configuration. Make sure that the
modem settings are correct, referring to Figure 4-6 for the correct configuration
values. Refer to the Boca 14.4Kbps V32bis MODEM manual for more information
about configuring the modem.
