AT+FDT Data Transmission
Used for FAX class 2 only
This command requests the ME to transmit a Phase C page. When the ME
is ready to accept Phase C data, it issues the negotiation responses and
the CONNECT result code to the application.
In Phase B, this command releases the ME to proceed with negotiation,
and releases the DCS message to the remote station.
In Phase C, this command resumes transmission after the end of a data
stream transmitted before.
