!AVEXTPCMSEL?
<profile>
!AVEXTPCMSEL
= <profile>, <value>
Supporting Mini Cards:
• MC8775V
Note: This command is not used
for newer voice-supporting

— audio profile IDs 6 and
7 are now available for PCM
audio in other commands.
Query / set external PCM interface for profile
This command enables or disables the external PCM interface for a
specific audio profile—the change takes effect after the modem is reset.
Usage:
• AT!AVEXTPCMSEL?<profile> returns the current status (<value>)
of the external PCM interface for the specified <profile>
• AT!AVEXTPCMSEL=<profile>, <value> enables or disables
(<value>) the external PCM interface for the specified <profile>
Parameters:
<profile> (audio profile number)
• 0 = Handset
• 1 = Headset
• 2 = Car kit
• 3 = Speaker phone
• 4 = Auxiliary
• 5 = TTY
<value> (external PCM interface state)
• 0 = Disable
• 1 = Enable
Note: The following commands affect a specified profile’s internal
codec—they have no effect if that profile’s external PCM interface is
enabled:
!AVCODECRXG, !AVCODECSTG, !AVCODECTXG, and
!AVMICGAIN. To use these commands, you must disable the profile’s
external PCM interface and then reset the modem.
