Command: +VLS Analog Source/Destination Selection
Description: This command causes the modem to select one or more source/destinations
of the analog data.
Syntax: +VLS=
Defined Values: Decimal number corresponding to the selected analog
source/destination hardware configuration (see Table 6-5).
Response:
Example: 0 For the default setting.
Reporting Supported Range of Parameter Values:
Command: +VLS=?
Response: ,,,,
Where each event subparameter is a hex number the represents an event bit
field of the reporting capabilities of each state. (See Table 6-6):
Identifies the modem analog source/destination hardware
configuration.
A made up of Primitives,
, , and event>subparameters are the DCE event reporting capabilities for the Voice
Transmit State, Voice Receive State, and the Voice Command State,
respectively. Each of the event reporting subparameters is a hex number that
represents an event bit field. The hex number format is defined in Table 6-6);
a one in the bit field indicates that the DCE can report the associated event.
Each of the possible hardware configurations has its own , ..., event> description line (the above form description shows just one). A
terminates each description line.

ERROR The value is out of range, or if the modem cannot service the
request in the subparameter.
