Vertical Resolution Format Conversion +FVRFC
Class 2.0/2.1 Not Applicable
Class 2
Write syntax: +FVRFC=<value>
Valid values: 0, 1, 2
Default value: 0
This parameter determines the modem response to a mismatch between the vertical
resolution negotiated for the facsimile session, reported by the +FCS:VR
subparameter, and the Phase C data desired by the host, indicated by the optional
+FDT:VR subparameter, or the +FIS=VR subparameter for +FDR operation.
FVRFC=0 Disables mismatch checking. The host must check the +FCS:VR
subparameter, and transfer matching data.
FVRFC=1 Enables mismatch checking. An implied +FKS command is executed
on mismatch detection.
FVRFC=2 Enables mismatch checking, with resolution conversion of 1-D data in
the modem. An implied +FKS command is executed on 2-D mismatch
detection.
Data Compression Format Conversion, +FDFFC
Class 2.0/2.1 Not Applicable
Class 2
Write syntax: +FDFFC=<value>
Valid values: 0
Default value: 0
This parameter determines the modem response to a mismatch between the data
format negotiated for the facsimile session, reported by the +FCS:DF subparameter,
and the Phase C data desired by the host, indicated by the optional +FDT:DF
subparameter, or the +FIS=DF subparameter for +FDR operation.
FDFFC=0 Disables mismatch checking. The host must check the +FCS:DF
subparameter, and transfer matching data.
Page Length Format Conversion, +FLNFC
Class 2.0/2.1 Not Applicable
Class 2
Write syntax: +FLNFC=<value>
Valid values: 0, 1, 2
Default value: 0
This parameter determines the modem response to a mismatch between the page
length negotiated for the facsimile session, reported by the +FCS:LN subparameter,
and the Phase C data desired by the host, indicated by the optional +FDT:LN
subparameter, or the +FIS=LN subparameter for +FDR operation. A mismatch would
require clipping or scaling a longer format to a shorter one.
FLNFC=0 Disables mismatch checking. The host must check the +FCS:LN
subparameter and transfer matching data.
FLNFC=1 Enables mismatch checking. An implied +FKS command is executed
on mismatch detection.
FLNFC=2 Enables mismatch checking, with page length conversion of 1-D data
in the modem. An implied +FKS command is executed on 2-D
mismatch detection.
