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:

evaluating the serial RING message)
