 *   pdp_addrp          Pointer to PDP address to use when called for IP
 *                      over GPRS. Must be null when called for IP
 *                      over CSD/PPP.
 *   peer_address       IP address of the peer, or a null pointer to indicate
 *                      the peer address is unknown. Only valid with IP over PPP.
 *   mtu                Size of the maximum transfer unit or zero if unknown.
 *   callback_function  Function to call after configuration is completed;
 *                      result can be AT_FAIL or AT_CMPL. May be null.
