Data Transmission
Class 2.1 +FDT
Syntax: +FDT<CR>
The FDT command requests the modem to transmit a Phase C page. It is issued at
the beginning of each page, either in Phase B or in Phase D. When the modem is
ready to accept Phase C data, it issues the negotiation responses and the
CONNECT result code to the host. Negotiation responses are controlled by the +FNR
subparameters.
In Phase B, the +FDT command releases the modem to proceed with negotiation,
and to release the DCS message to the remote station. In Phase D, the +FDT
command resumes transmission after the end of a previous page.
Class 2 +FDT
Syntax: +FDT[=DF,VR,WD,LN]<CR>.
