C.2.3 Calling number ID presentation +VCID
The command refers to an integer that allows a called party to enable or disable (<n>=0) the reporting of the ID of
calling parties, and specifies the method of presentation of the ID. This is basically the same as GSM/UMTS
supplementary service CLIP (Calling Line Identification Presentation). The presentation may be either formatted
(<n>=1) or unformatted (<n>=2):
- Formatted presentation : data items are reported in the form of <tag>=<value> pairs.
<tag>
<value>
DATE MMDD (month, day)
TIME HHMM (hour, minute)
NMBR calling number or P or O (P = number is private, O = number is unavailable)
NAME subscription listing name
MESG data from other (unknown) tags
- Unformatted presentation : here the data is presented in ASCII hex as printable numbers.

C.2.4 Receive gain selection +VGR
This refers to the amplification by the TA of audio samples sent from the TA to the computer. The command operates
on an integer <n>, range 0...255. Values larger than 128 indicate a larger gain than nominal. Values less than 128
indicate a smaller gain than nominal. The entire range of 0...255 does not have to be provided. A value of zero implies
the use of automatic gain control by the TA.

Command
Return
+VGR=<n>
+VGR?
<n>
+VGR=?
(list of supported <n>s)
C.2.5 Transmit gain selection +VGT
This refers to the amplification by the TA of audio samples sent from the computer to the TA. The command operates
on an integer <n>, range 0...255. Values larger than 128 indicate a larger gain than nominal. Values less than 128
indicate a smaller gain than nominal. The entire range of 0...255 does not have to be provided. A value of zero implies
the uses of automatic gain control by the TA.
