A string which specifies the preferred modem carrier to use in originating or answering a
connection.
and upper case letters.

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.)
Numeric values which specify the lowest (
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 3-2.
Actual values will be limited to possible values corresponding to the entered
