13 // Description: |
|
14 // The execution command is used to attach the MT to, or detach the MT from, the GPRS |
|
15 // service. After the command has completed, the MT remains in V.25ter command state. |
|
16 // If the MT is already in the requested state, the command is ignored and the OK |
|
17 // response is returned. If the requested state cannot be achieved, an ERROR or +CME |
|
18 // ERROR response is returned. Extended error responses are enabled by the +CMEE |
|
19 // command. |
|
20 // Any active PDP contexts will be automatically deactivated when the attachment state |
|
21 // changes to detached. |
|
22 // The read command returns the current GPRS service state. |
|
23 // The test command is used for requesting information on the supported GPRS service |
|
24 // states. |
|
25 // +CGATT= [<state>] |
|
26 // <state>: indicates the state of GPRS attachment |
|
27 // 0 ?detached |
|
28 // 1 ?attached |
|
29 // Other values are reserved and will result in an ERROR response to the |
|
30 // execution command. |
