Chapter 7: AT Commands and Registers
)M n Power Level Adjustment
for Cellular Telephone Connections
)M0 For central site modems: Auto-adjustment (adjusts power level if
remote modem is set to )M1). Use for MNP 10 modems that will
connect to both cellular telephone and non-cellular telephone site
modems.
)M1 For cell-side cellular modems: Forces power-level adjustment.
Adjusts the power levels during link negotiation for reliable
connections to accommodate signalling requirements of cellular
telephone equipment.
-M n MNP Class Connect Messages
-M0 Disables MNP Class connect messages.
-M1 Enables MNP Class connect messages.
Determines whether MNP Class connect messages are displayed.
The -M1 setting overrides the \V command setting for long form
connection result codes and the W command for serial-port
connect messages.
When -M1 is set and an MNP connection established, the connect
message is CONNECT MNPn/x, where n equals the MNP Class
(from 1 to 10) and x equals the type of data compression used
(V.42bis or MNP Class 5). If )M1 is set, the message is
CONNECT MNPn/y/x, where y equals CELLULAR. If the
modems do not negotiate compression, the message is
CONNECT MNPn.
During LAPM V.42bis connections when -M1 is set, the connect
message is CONNECT LAPM/V42BIS. During LAPM
connections with no compression active, the message is
CONNECT LAPM.
When -M1 is set, the message during normal and direct
connections is CONNECT.
The modem ignores this command with short-form result codes
enabled by V0.
Setting X0 will also override the -M setting by displaying only
CONNECT.
See also "Result Codes" in Chapter 6 for a complete list of
connect messages and result codes.
