Pic to GSM Phone connection (HSerin problems)

Sorry.... would it be possible to add comments to each of the following lines:

You have to make your own subroutine to compare byte to byte the two string array. Like that:

i=0
while i less_than gsmbuffer_length (I cant sen the less character! Why?)

if gsmbuffer[i]=compare_array[i] then
'gsmbuffer[i]=0
i=i+1
else
goto wrong_sms
endif
wend
correct_sms:
'your code here

wrong_sms:
'your code here

Could you give me an example using the SMS keyword: "switch on" in order to switch on an LED.

Thanks again.

Regards,
Royce

The commands used in the small piece of code are very elementary. So you have to read the manual because all the answers are in there.

I cannot explain how an If-Then-EndIf statement is syntaxed or how is working. The code I gave you is very very easy and basic I could say.

It is comparing one element of the array gsmbuffer at a time with one element of the other array. If it succeeds then it is moving on to the part of the program labeled:

correct_sms:
'you add your code here

If it does not succeed then it is moving on to the part of the program labeled:

wrong_sms:
'you add your code here

Try to write some code and see what happens. One part at a time...

Thanks Ioannis. I will do my homework.

Hello all,
I have been doing something similar with an Ericsson T68I phone.
I communicated at 1200 buad and use AT command set.
I am NOT trying to send SMS, but DTMF tones. I am getting the phone to dial by using the access keypad AT command (rather than ATD command, which for some reason wouldn't work) and then activating send DTMF tones. Sorry I can't remember what the AT for these are, but what I dis was successful withoput too much trouble. Simple serout at N1200 (without MAX232 chip) was the most successful from a 4MHz 'F84. The T68I is autobaud so will talk at most baud rates above 1200.
