Command Reference
Data Command Set - 60
S95 bit 5 is reset to 0 for +DR=0 and is set to a 1 for +DR=1. The more recent
setting of +DR or S95 bit 5, and the W command setting, determines the actual
data compression result code reporting (see S95 Parameter and W Command).
Syntax
+DR=[<value>]
Defined Values
<value> decimal number corresponding to the selected option:
0 Data compression reporting disabled (no +DR result code
transmitted).
1 Data compression reporting enabled (+DR result code
transmitted). (Default.)
Reporting Current or Selected Values
Command: +DR?
Response: +DR: <current value>
Example: +DR: 1 For the default setting.
Reporting Supported Range of Parameter Values
Command: +DR=?
Response: +DR: (<value> range)
Example: +DR: (0,1)
+DR: <type> Intermediate Result Code
The +DR: <type> reported represents the current (negotiated or renegotiated)
modem-modem data compression type. If enabled, the intermediate result code is
transmitted at the point after error control negotiation (handshaking) at which the
modem has determined which data compression technique will be used (if any)
and the direction of operation. The +DR intermediate result code, if enabled, is
issued after the Error Control Report (+ER) and before the final result code (e.g.,
CONNECT).
The format of this result code is:
