Severe Bug: N73 AT command support broken

N73 (and several other nokia phones, too) understands only parts of the command set.

Example dialogs:

AT+CPMS?                                                                        
+CPMS: ,,,,,,,,                                                                                                                                                 
OK                                                                               

AT+CPMS=?                                                                       
+CPMS: (),(),()                                                                                                                                                 
OK                                                                              

Many other commands (e.g. in contact management) don't work either. I found no documentation regarding this behaviour.

I feel that Nokia should release information about how this phone is to be used. I wouldn't recommend anyone to pay in excess of 200€ for a phone that doesn't do what it's supposed to.

use lower speed in USB COM port

Hi,

i had the same problem above, and all i had to do was, search for the USB COM port that the phone was using, and lower the speed (i used 9600). because i only need to send a few SMS messages, i left the speed that low. after changing the speed, SMS and other commands work OK.

regards,

Oscar.

command set differs from phone to phone

e.g. on some phones some commands are missing and not all commands are listed here and on referenced links...
