Test command
Syntax
AT+

OK
Write command
Syntax
AT+
XDATACHANNEL
=<mode>,
<csd_gprs_flag>,
<ctrl_tid_path>,
<tid_path>
[,<connect_flag>
[,<cid>]]
Response
OK
or
+CME ERROR: <err>
Parameters
<mode> 0 Disable routing
1 Enable routing
2 Query current setting for the channel where the command is executed
(other parameters will be ignored)
<csd_gprs_flag> 0 Configure channel for a CSD connection
1 Configure channel for a GPRS connection
<ctrl_tid_path> Terminal for which the data routing mechanism shall be enabled in
string format (e.g.: “/mux/5”)
<tid_path> Terminal to which a data call shall be routed in string format (e.g.: “/mux/5”)
<connect_flag> 0 No reporting on the data channel (neither CONNECT nor NO
CARRIER)
1 Reporting on the data channel enabled (CONNECT and NO
CARRIER)
2 Reporting on the control channel enabled (CONNECT and NO
CARRIER)
<cid> Numeric parameter which specifies a particular PDP context definition (see the
+CGDCONT and +CGDSCONT commands)
Notes
The control channel must be in OPEN state when the +XDATACHANNEL
command is sent.
+XDATACHANNEL settings will only apply while control channel DLC is OPEN
and will be reset as soon as DLC is closed.
When this command is sent with <cid> parameter, then the data channel
(<tid_path>) must be in OPEN state and the given <cid> should already be defined.
If the <cid> is deleted or undefined, the XDATACHANNEL settings pertaining to
the <cid> are not retained.
Connection must be established (start and stop) through <ctrl_tid_path> for data to
be properly routed.
+XDATACHANNEL query (mode=2) does not return the <cid> associated with the
control channel, as the data routing of a control channel can be configured for
multiple <cid>s.
