Modem Emulator
The serial Ethernet gateway can emulate a modem. It provides a series of AT commands
for this. A modem will be emulated for each connection type with this function. If an
outgoing connection has been triggered by the ATD command, the modem emulator will
always be used, even if it is disabled. The following AT commands are supported:
