Description
Ignore connection status, keep DCD high and LED3 pin low (ie ON).
DCD tracks the status of the data connection, raised when the call
is connected, lowered when cleared. LED3 pin tracks the inverse status
of the DCD pin (ie high when data connection is cleared).
&D (Data Terminal Ready)
Format:AT&Dn<CR>
Determines the CMX228 operation if DTR is lowered during a call.
Suffix n

Description
No action
2 (default)
B or D-channel data call is cleared and auto-answer is suspended until
DTR is raised again.
If &D2 is set and DTR is low when an incoming call is received, the call is accepted and Ring
Indication is sent to the DTE. If an incoming call has been accepted and &D2 is set when DTR is
lowered, the call is cleared.
