Chapter 8 – Communication Commands
V.42bis Data Compression Report +DR
Description:
Syntax:
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:
+DR: NONE Data compression is not in use
+DR: V42B Rec. V.42bis is in use in both directions
+DR: V42B RD Rec. V.42bis is in use in receive direction only
+DR: V42B TD Rec. V.42bis is in use in transmit direction only
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>
Command
AT+DR=1
Note: Reporting enabled
AT+DR?
Note: Display the current value
AT+DR=?

Hang-Up 1x Data Command +WCHD
Description:
Syntax:
The AT+WCHD command is used by the application to disconnect all 1x data calls. The
alternative is to use the DTR pin.
Command Syntax: AT+WCHD
Command
AT+WCHD
Note: Ask for disconnection
