#M – Received CLID

Shows the called line identification (CLID) that is received with an incoming call – this is
the number of the called party addressed on the local S-bus (selected msn).

AT#M

! +MS – Modulation Selection

This extended-format compound parameter controls the manner of operation of the modu-
lation capabilities in the modem. It accepts six subparameters:
AT!+MS=[<carrier>[,<automode>[,<min_tx_rate>[,<max_tx_rate>[,<min_rx_rate>[,<ma
x_rx_rate>]]]]]]
Where: Possible <carrier>, <min_tx_rate>, <max_tx_rate>, <min_rx_rate>, and
<max_rx_rate values are listed below.

Defined Values
<carrier>

A string which specifies the preferred modem carrier to use in originating

or answering a connection. <carrier> values are strings of up to eight
characters, consisting only of numeric digits and upper case letters.
<carrier> values for ITU standard modulations take the form:
<letter><1-4digits><other letters as needed>.

<automode>

A numeric value which enables or disables automatic modulation
negotiation (e.g., ITU-T V.32 bis Annex A or V.8).
0 = Automode disabled.
1 = Automode enabled. (default)

<min_rx_rate> Numeric values which specify the lowest (<min_rx_rate>) and highest

and

rate at which the modem may establish a receive connection. May be

<max_rx_rate>

used to condition distinct limits for the receive direction as distinct from
the transmit direction. Values for this subparameter are decimal encoded,
