+MR - Modulation Reporting Control
This extended-format numeric parameter controls whether or not the extended-
format +MCR: <carrier> and +MRR: <rate> intermediate result codes are
transmitted from the modem to the DTE (Table 3-14). If enabled, +MCR: <carrier>
and +MRR: <rate> intermediate result codes represent the current (negotiated or
renegotiated) modulation <carrier> and <rate> that are transmitted at the point
during connect negotiation (handshaking) at which the modem has determined
which modulation and rate will be used, i.e., before any Error Control or Data
Compression reports are transmitted, and before any final result code (e.g.,
CONNECT) is transmitted.
S95 bit 2 is reset to 0 for +MR=0 and is set to a 1 for +MR=1 or +MR=2. The more
recent setting of +MR or S95 bit 2, and the W command setting, determines
modulation result code reporting (see S95 Parameter and W Command).
Syntax
+MR=[<value>]
Defined Values
<value> A decimal number corresponding to the selected option:
0 Disables reporting of modulation connection (+MCR: and +MRR:
are not transmitted).
1 Enables reporting of modulation connection (+MCR: and +MRR:
are transmitted). (Default.)
2 Enables reporting of modulation connection (+MCR: and Receive
Rate Only: are transmitted).
