Reference Guide for the Model XM128 ISDN Digital Modem
4-2 Configuration
The setup procedure for the Model XM128 modem needs to be done only once because the
settings are stored in the nonvolatile RAM of the modem and turning the power off does not erase
the information. The only time you have to reconfigure your line is when you perform a hardware
reset or when you change options on your ISDN line.
Table 4-1 shows a list of example terminal programs for different operating platforms. For
instructions on how to use a terminal program, refer to the instructions that came with the program.
Understanding AT Commands
AT commands configure and control the Model XM128 modem through a terminal program.
Command statements are usually sent to the modem from the computer keyboard.
Command statements must be written in a specific form in order for the Model XM128 modem to
recognize them. A command statement begins with the letters AT or at. It is then followed by one
or more commands and the Enter key.
AT commands can be issued only when the Model XM128 modem is in command or offline mode.
After the Model XM128 modem has established a connection with the remote device, it goes into
online mode, and the characters sent from your computer (through the modem) are transmitted
to the remote device.
Note: If you perform a hardware reset and have to reenter the SPID number(s) and switch
type again, it is easier if you write down or store all the relevant information so it can be
easily retrieved.
