    Hello,
    as far as I know, I read again the manual, it's not possible to set baud speed to be used through the port. The only set possible for baud speed is if you want to connect to the internet (wap). I tried in any case to set it at 9600 but it did not work.
    I checked the at command manual and i did the following check with the cable and hyperterm (19200,8,N,1):
    AT+CBST?
    > +CBST:0,0,1 the phone is in autobauding
    then i typed:
    AT+CBST 7,0,1
    AT+CBST?
    > +CBST:7,0,1 the phone is at 9600 baud
    Great, I thought, now i change the hyperterm setting from 19200 to 9600 and let's see !!
    Nothing, exactly like before, at + enter, no answer back
    I reset the hyperterm to 19200 and i type
    AT+CBST?
    > +CBST:7,0,1 the phone is still at 9600 baud

    Seen that the phone is in autobauding and it's not possible to set via menu
    I'll try to add to the code this:

    >>CUT
    BAUD = 84 ' 9600,8,N,1(True,driven)

    Start:

    SerOut2 TX, BAUD, ["AT+CBST=7,0,1",13] ' <-------------------------------
    SerOut2 TX, BAUD,["AT",13]
    Pause 500
    SerOut2 TX, BAUD, ["AT+CMGF=1",13] ' Use TXT Mode
    Low LED ' Turn OFF Status LED
    >>CUT

    I have some doubts but I will try
    What do you think you guys ??
    Bye
