Chapter 4 – Voice Commands

Command:	+VEM=?	Report Event Reporting and Masking Capabilities
Description:	The +VEM=? command returns four lines of modem event reporting/masking capability
	information, followed by the OK result code. The first line indicates the Service Level

supported by the modem (though the modem may support more than the capabilities displayed). The next three lines report the capability of the Voice Transmit mode, Voice Receive mode, and the Voice Command mode, respectively. Each line is a hex value that is the bit-wise OR function across all of the supported compression methods and across all analog source/destination hardware configurations (i.e., all +VLS settings) for the specified mode. Note that the displayed hex values are not connected to the <mask> parameter in the +VEM and +VEM? commands.
