    7-Bit Encoded Text Header Message

    Hi

    Thanks for reading this. I basically have two questions that are unrelated:

    1) Is it possible to have a 7-bit encoded text header message and if so does this mean the actual text header part (as this is effectively part of the user data) is encoded as 7-bits and needs unpacking to 8-bits before you can parse for "//SCKL......." ? Can anyone supply an example of such a message ?

    2) What is the cancel-command-specifier used for in ringing tone programming. I cannot think of a viable use or scenario in which it would be used. If this is used is it possible to again supply an exmaple byte stream ?

    Again thanks for reading this and any information will be grately appreciated

    Regards

    Dave

    1)"//SCKL... is using special text format that should not be mixed with the binary format since the text is allready using 7 bit data
    and there is no actual user data header at all.
    User data header can be in the beginning of user data which has 7bit/8bit/UCS2 data coding scheme. In all cases the coding of header is similar. Only in case of 7 bit data the actual data after header starts from the next bit septet boundary of the user data field.
    2)No idea...

    Yes they are 7 bit coded data. That is the normal text format in
    short messages. I don't know if the phone understands the same
    text message coded to 8 bit format using 8 bit data coding scheme.
    Binary format uses normally less space and is supported in most
    phone models.
