XT55 AT Command Set - Wireless Data Modules

XT55 AT Command Set11.17 ATD*98#s11.17 ATD*98# Request GPRS IP serviceThis command causes the MT to perform whatever actions are necessary to establish a communication betweenthe TE and the external PDN.The V.250 'D' (Dial) command causes the MT to enter the V.250 online data state and, with the TE, to start thelayer 2 protocol.GPRS attachment and PDP context activation procedures may take place prior to or during the PDP startup ifthey have not already been performed using the AT+CGATT and AT+CGACT commands. If the context to be usedis already activated, it will be deactivated first. This ensures that the right context parameters will be used (e.g.QoS changes since the last context activation).To confirm acceptance of the command before entering the V.250 online data state command will respond withCONNECT.When the layer 2 protocol has terminated, either as a result of an orderly shut down of the PDP or an error, theMT enters V.250 command state and returns NO CARRIER (for details refer to Section 11.6.1, Automatic deactivationof PDP context during dial-up PPP).SyntaxExec CommandATD*98[* ]#Response(s)CONNECTNO CARRIERReference(s) PIN ASC0 ASC1 MUX1 MUX2 MUX3 Charge LastGSM 07.07 % % § % § § ! ! %Parameter Description (num)Parameter specifies a particular PDP context definition (see AT+CGDCONT command).
