    How DCS value had been changed?

    Hi,
    I have a problem for sending SMS from my GSM modem in text mode. It sends class 0 message to a mobile phone because of change in DCS value. It should be 0 by default. I did not set this value.

    So, i would like to know that this change of DCS value is due to bad communication of modem or any other reason?

    RE: How DCS value had been changed?

    You can set DCS value in Text mode using +CSMP command.
    AT+CSMP? will give you present settings. DCS is the
    fourth parameter in +CSMP command.
    AT+CSMP=fo,vp,pid,dcs
    I don't know what has caused the DCS to change.
    More about DCS in GSM specification 03.38.
