)Mn 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.

-MnMNP Class Connect Messages

-M0Disables MNP Class connect messages.

-M1 Enables MNP Class connect messages.

Determines whether MNP Class connect messages are displayed. The -M1setting 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 -M1is 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.
