Can you help me out with one more thing, that is how can i read an sms and store it in an array, lets say an sms contains hi, then which syntax should i use, or if there is some alternative better way...

Syntax1:
buffer var byte[90]

serout portb.6,t300,["at+cmgr=1",13]

SERIN portb.7,t300,1000,oops,["+"],buffer[0],buffer[1]


Syntax2:
buffer var byte[90]

serout portb.6,t300,["at+cmgr=1",13]

for x=1 to 3
SERIN portb.7,t300,1000,oops,buffer(x)
next x


or is there any other way to store the sms in the array,

thanks a lot

You must send this sms : "123 HI" (123 is the pointer).

Then I suggest the following code:

buffer var byte[90]

SEROUT2 portb.6,3313,["AT^SMGR=1",13] ' Call for sms

SERIN2 portb.7,3313,1000,oops,[Wait ("^SMGR:" ),Str buffer \ 5] ' (3313 is baud rate = 300 see PBP manual pag 133)

if buffer[1]=48 and buffer[4]=48 then oops ' if no sms has been received then jump to oops label

SERIN2 portb.7,3313,[Wait ("123"),Str buffer \ 3] ' If sms is present wait for pointer then load array

If everything work, then you should find:

buffer[0]=32 (space)
buffer[1]=H
buffer[2]=I

Hello, i'm stucked at the point that our dear PIC works on 5V, and thus definitely the serin/serout would also generate high and low pulses of 0-5v, while the GSM module which i'm having (SIM508) posses serial transmission module of VMax being 3V...and it's been quoted to use a level converter where necessary, so can anyone help me out with this...
can i use MAX233 in between or would there be any other procedure to follow...

Hello Jamshid Dastur, I think a simple transistor would work to switch data @ 5 volts, keeping in mind it would invert the data.

Hi Joe, are you sure about MAX ic that its not a serial decoder, and just a level shifter, if so...then i can simply use a zener diode to drop voltage and a 40XX buffer ic to up the level without any inversion...
