Response

OK/ERROR/+CME ERROR

Parameter:

<subtype>       see Test commnd

<actNumber>   see Test commnd

<maxNumber> see Test commnd

Note:

-It is not possible to upload data when a call is active or in progress.

 If a call is active the mobile responses with +CME

ERROR: PHONE BUSY and the  actual upload sequence is aborted and all data packets are discarded.

-If uploaded data is not useable (e.g. wrong data format) the mobile responses with +CME ERROR: INV CHAR IN TEXT after the last packet is uploaded.

-To get the extended +CME-ERROR-responses AT+CMEE=2 has to be sent before.

Otherwise the mobile respones only with ERROR .  (see GSM07.07)

-If <actNumber> and <maxNumber> during the upload are omitted, the mobile aborts the whole input sequence for the current subtype.

-If <actNumber> is 0 during the upload and <maxNumber> is ommitted, the mobile deletes the actual record with index <subtype>

-Packets have to be uploaded in the right order!

-Limitation:The maximum pdu size is 176 bytes (or 352 characters)
