This command returns the results of data compression capability. If data reporting is enabled, this
command returns the data compression type of an incoming or outgoing data call. Otherwise, the
command returns NONE.
The intermediate result code represents current DCE-DCE data compression type. The syntax for
+DR reporting is: +DR<result>, and the result code is defined as follows:
The +DR intermediate result code, if enabled, is issued before the final result code and after the
service report control +CR.
Command syntax: AT+DR=<val>
This syntax is for setting the +DR reporting method.
