Command: +FCR
Capability to Receive
Description:
+FCR=0
indicates that the DCE will not receive message data. This can be
used when the DTE has insufficient storage. The DCE can send and can be
polled for a file.
+FCR is sampled in CCITT T.30 Phase A and Phase D.
Write syntax:
+FCR=<value>
Valid values:
0 or 1
Default value:
0
Command: +FPTS= Page Transfer Status
Description:
The +FPTS parameter contains a value representing the post page response,
including copy quality and related end-of-page status. These values
correspond to post page response messages defined in T.30. The receiving
DCE sets this parameter after it receives a page of Phase C data. The
transmitting DCE sets this parameter with the status reported by the receiving
station. The DTE may inspect or modify this parameter.
The set of <ppr> values is defined in Table 3-4. These values are also
reported in the +FPTS response to the +FDR command.
Write Syntax:
+FPTS=<ppr>
Valid values:
1, 2, 3, 4, 5
Default value:
0
Command: +FCQ
Copy Quality Checking
Description:
This parameter controls Copy Quality checking by a receiving facsimile DCE.
The DCE rFCQ=0 which indicates the DCE does no quality checking.
The DCE will generate Copy Quality OK (MCF) responses to complete pages,
and set +FPTS=1.
Write syntax:
+FCQ=<value>
Valid values:
0
Default value:
0
Command: +FPHCTO DTE Phase C Response Time-out
Description:
The +FPHCTO command determines how long the DCE will wait for a
command after reaching the end of data when transmitting in Phase C. When
this time-out is reached, the DCE assumes there are no more pages and no
documents to send. It then sends the T.30 EOP response to the remote
device.
Write syntax:
+FPHCTO=<value>
Valid values:
0 - 255, 100 millisecond units.
Default value:
30
Command: +FAXERR T.30 Session Error Report
Description:
his read-only parameter indicates the cause of the hangup. Table 3-5 shows
the valid values for this parameter as well as the meaning of the each value.
+FAXERR is set by the DCE at the conclusion of a fax session. The DCE
FAXERR to 0 at the beginning of Phase A off-hook time.
Read syntax:
+FAXERR= <table value>, read only
Valid values:
0 - 255
