Class 2.0/2.1

	Chapter 3 – Fax Class 2 Commands

Format conversion, +FFC
Class 2.0/2.1
Write syntax:	+FFC=<vrc>,<dfc>,<lnc>,<wdc>
Valid values:	see table below
Default values:	manufacturer’s option

Mandatory values: 0,0,0,0

This compound parameter determines the modem response to mismatches between the Phase C data delivered after the +FDT command and the data format parameters negotiated for the facsimile session. For mismatch checking, the modem depends on the host to indicate the data format with embedded <DLE><format> character pairs.

If these format indicators are not provided, the modem shall assume that the format is as negotiated for that session.

For each subparameter, value 0 determines that mismatch checking is disabled, and all format codes of this type are ignored. Value 1 determines that mismatch checking is enabled, with session termination if the format codes do not match the negotiated format reported in +FCS: responses. Other values enable degrees of format conversion. Unspecified values are reserved.
