Command
Description
Set
[Function]
The Set command activates/deactivates the specified PDP context(s). When the
command is completed, the ME remains in V.25 command state. If any PDP context is
already in the requested state, the state for that context remains unchanged. If the
requested state for any specified context cannot be achieved, an ERROR or +CME
ERROR response is returned. Extended error responses are enabled by the +CMEE
command. If the ME is not GPRS-attached when the activation form of the command is
executed, the ME first performs a GPRS attach and them attempts to activate the
specified contexts. If the attach fails, the ME responds with an ERROR or, if extended
error responses are enabled, with the appropriate failure-to-attach error message.
