Various modems have different sets of commands. In this dialog, you can
fine-tune the commands sent to your modem and the possible responses your modem
can answer with.
Most modems are Hayes-compatible. These common AT commands require no
modification. There are exceptions, however. For example, sCmdDevSpecificInit
line at the bottom of the table contains device-specific initialization
settings (S registers modifications etc.)
There are several Voice commands' extensions to standard Hayes-compatible
command set. Here you can adjust those commands, including sVoiceDevSpecificInit
string being sent to the modem after entering voice mode.
