5.15.2 Description

The EXECUTION command returns all messages from <mem1>, which are in the
state specified by the parameter <stat>. If the message state is "Unread message that
has been received", the state of the message in the storage will be converted to "Read
message that has been received" after the command is executed successfully.
When the <stat> takes on the default value, the EXECUTION command is equivalent
to the SET command +CMGL=0.
The TEST command returns all the supported stat values.
