help me please

Sorry I don't know anything about this phone.

When you connect the phone to your PC to verify it's sending
data to hyperterminal, how are you connecting the phone to
your PC serial port?

When you connect your phone to the PIC, how are you making
this connection?

[MICOCALI]

I connect phone with hyper... with convertitor rs 232 ttl (max 232 ) and
i set Hyper.. with 9600 8 N 1
but when i send command at+cmss=1 the phone send message very well
WY for you

[Bruce]

OK, but how are you connecting the phone to your PIC?

[MICOCALI]

direct with two resistor

Miiiiiiiiiip this is why. you must still use the Max232 ic to invert the serial data. OR, but it bet that will not work 100%, use serin/serout in inverted mode.

[MICOCALI]

the bit 14 is the register for setting the serial comunication at inverted mode but wich is the parameter for setting 9600 baud,no parity ,inverted.
For example mode=84 is 9600,no parity,true
thank you.
where is if possible search this parameter ,because i search in the data sheet but i dont watch never

[mister_e]

so now it imply that you use SERIN2/SEROUT2 or else. chances are that you'll never find anything in the datasheet since it's a PBP statement. You'll find the result in the APPENDIX A at the end of your PBP manual... there you'll find the right setting for SERIN2/SEROUT2 wich is.....16468

For SERIN/SEROUT you'll use 6

You can't tell to HSERIN/HSEROUT to drive inverted since it use the internal PIC hardware.
