Defined Values

A string which specifies the preferred modem carrier to use in

originating or answering a connection. values are
strings of up to eight characters, consisting only of numeric
digits and upper case letters. values for ITU standard
modulations take the form: <1-4 digits>needed>. Defined values are listed in Table A-3.

A numeric value which enables or disables automatic

modulation negotiation (e.g., ITU-T V.32bis Annex A or V.8).

0 =

Automode disabled.

1 = Automode enabled. (Default.)

and

Numeric values which specify the lowest () and
highest () rate at which the modem may
establish a receive connection. May be used to condition
distinct limits for the receive direction as distinct from the
transmit direction. Values for this subparameter are decimal
encoded, in units of bit/s. The possible values for each
modulation are listed in Table A-3. Actual values will be limited
to possible values corresponding to the entered and
fall-back as determined during operation. (Default =
lowest () and highest () rate
supported by the selected carrier.)

and

Numeric values which specify the lowest () and
highest () rate at which the modem may
establish a transmit connection. Non-zero values for this
subparameter are decimal encoded, in units of bit/s. The
possible values for each modulation are listed in Table 3-3.
Actual values will be limited to possible values corresponding
to the entered and fall-back as determined
during operation. (Default = lowest () and highest
() rate supported by the selected carrier.)

Reporting Current or Selected Values
Command: +MS?
Response: +MS:,,,

Note: The current active settings are reported under control of the +MR parameter.
Example:

+MS: K56, 1,300,33600,300,56000

For default values. This example allows maximum system flexibility to determine
optimal receive and transmit rates during operation.
Reporting Supported Range of Parameter Values
Command: +MS=?
Response:

+MS: (< carrier> range),( range),(
range), ( range), ( range),
( range)

Example 1:

+MS:(B103,B212,V21,V22,V22B,V23C,V32,V32B,V34,
K56,V90),(0,1),(300-33600),(300-33600),(300-56000),(300-
56000)

Example 2:

+MS:(B103,B212,V21,V22,V22B,V23C,V32,V32B,V34,
V90,V92),(0,1),(300-33600),(300-33600),(300-56000),(300-
56000)

Result Codes

OK Valid subparameter string

ERROR Otherwise.
