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 ports 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 to the
modem.
Proceed as follows:
1. Connect one end of an RS-232 cable to an RS-232, serial-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.
