&D0 * DTR Override
If the local DTE does not provide the DTR signal on the RS-232 interface, the Modemulator
firmware can behave as if DTR is asserted with this command.
&D2 * DTR Normal Operation (default)
The DTR signal on the RS-232 interface behaves normally. If the Modemulator is currently in a
cellular or analog connection, and the DTR signal is de-asserted, the connection will be terminated.
Be sure to re-assert DTR before the next connection attempt.
