<Rx>
Set the diagnostic port to either UART2 or USB. The diagnostic port is used with tools like QPST,
QXDM, and WPST. These tools can run in conjunction with normal execution of the modem.
Command Syntax: AT+WDMX= <port>
<port>
This command is used to specify the behavior of the Data Carrier Detect (DCD) signal on the
modem DATA port. The factory default value is 2. The AT&F command restores the value to the
factory setting.

Hardware
The DCD signal is always asserted.
The DCD signal is asserted in a call and de-asserted when not in a call.
The DCD signal is always asserted except at the end of a call. At the end of a call, the
DCD signal is de-asserted for 1 second. Default is 2
