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
Note:
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, 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.

well as for remote dial up to the server for maintenance and administration.
