Reporting Supported Range of Parameter Values
Command: +VLS=?
Response: <label>,<devices>,<transmit
event>,<receive event>,<idle event>
Where each event subparameter is a hex number the represents an event bit field of the
reporting capabilities of each state. (see Table 5-6):
<label>
Identifies the modem analog source/destination hardware
configuration
<devices>
A <string constant> made up of Primitives,
<xxxx event>
<transmit event>, <receive event>, and <idle
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 5-6); a one in the bit field indicates that the DCE can
report the associated event.
Each of the possible hardware configurations has its own <label>, ..., <idle event>
description line (the above form description shows just one). A <CR><LF> terminates
each description line.

Result Codes
OK
<label> = 0-5,8-9,11,14,18-19.
ERROR
The <label> value is out of range, or if the modem cannot
service the request in the <label> subparameter.
