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.

If these format indicators are not provided, the modem shall assume that the format

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.
