The most important modem string is the initialization string because your network
device uses it to establish communications with your modem or ISDN TA. The
modem initialization string displayed is the modem or ISDN TA initialization
string entered in the Setup Wizard. For most analog modems, the Standard
Modem selection will work. For additional information, refer to the Modem
Settings information presented in Chapter 4.
