3.12 AT+FDT Data Transmission
Execute command
AT+FDT
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, the +FDT command releases the ME to proceed with negotiation,
and releases the DCS message to the remote station. In Phase C, the +FDT
command resumes transmission after the end of a data stream transmited
before.
