Hardware required when configuring

modems

To configure many modems, you use the Hayes-compatible AT command set.
NOTE:
If your modem uses a USB connection, use the USB p orts instead of the
serial port. Also, AT commands are not required, so you can skip this
section. Use the factory defaults.
Before you can enter AT configuration commands, you must first connect a
terminal or a PC with a keyboard, monitor, and terminal-emulation software t o the
modem.
Proceed as follows:
1. Connect one end of an RS-232 cable to an RS-232, ser ial-communications
port (often called a COM port) on the terminal or PC .
2. Connect the other end of the RS-232 cable to the modem.
3. If you are using a PC, start your terminal emulation software.
