Continue Document Reception
The DTE may issue a +FDR command in Phase D, which releases the post page
message, and indicates readiness to receive another page after receipt of a Multipage
(+FET:0) or PPS-NULL (+FET:3) message. The DCE response will be:
CONNECT
(<DC2> needed from DTE here)
<Phase C data stream)
<DLE><ETX>
+FPTS:<ppr>, <lc> [,<blc>, <cblc>]
+FET:<ppm>
OK
(DTE must issue +FDR command to release post page response)
If done receiving:
+FHNG: <hangup cause code>
OK
Continue page reception
Phase C Data Framing
Phase C data may be presented to the DTE in stream mode. The DCE will transfer a
stream of data to the DTE, followed by the <DLE><ETX> stream termination characters.
The DCE will filter the stream as described later in this appendix.
Phase C Data Format
The received data format is negotiated under T.30 reported by the
+FDCS:VR,BR,WD,LN,DF,EC,BF,ST response.
The DCE will delete the terminating RTC (6 EOLs) patterns.
<CAN> - Escape from Reception
From the +FDR command until the end of Phase D Date, the DCE is in a data transfer
state, and will not respond to DTE command characters. The DCE will respond to three
ASCII control characters: <DC1> (017) and <DC3> (019) flow control characters, and
cancel <CAN> (024).
Upon receipt of the <CAN> character, the DCE will terminate the reporting of received
data by sending trailing <DLE><ETX> characters to the DTE, and will then execute an
implied +FK command in order to conduct an orderly disconnection.
