Hi all:
I have a sumsung A670 phone,it is a CDMA phone,I use Bitpim to download file from this phone,from the log file,I know Bitpim use a special command:"AT$QCDMG",this command can transform serial port into diagnostic mode(DM),but A670 uses USB data port to communicate with other device,I am very confused by this phenomenon,because AT$QCDMG only transforms serial port into DM mode,this means that the cellphone should have serial port,but A670 only has USB port,it does not have serial port!
Thanks for your help in advance!
