Pic to GSM Phone connection (HSerin problems)

[Russell]

Connection
1.DKU-5 cable connected to the Nokia phone.
2.a male type connector connected to the other end of the DKU-5 cable
3.from that connector I set up the connection to the basic stamp2 as shown above.
4.by the following bs2 code I successfully sent sms
SEROUT 1, 16572,25, [ "AT+CMGF=1" , CR]
SERIN 3, 16572,[ WAIT ( "OK" )]
SEROUT 1,16572,25,["AT+CMGS=",34,"+880191787670",34,CR]
SERIN 3, 16572, [WAIT (">")]
SEROUT 1, 16572, [“hello”,CR]
SEROUT 1, 16572, [26,CR]
SERIN 3, 16572, [WAIT ("OK")]
DEBUG "ok"

MY PROBLEM NOW IS, I MADE SAME CIRCUIT WITH PIC16F84A TO SEND SMS. BUT IT IS NOT WORKING. MY PICBASIC PRO CODE IS OK. I THINK (SURE) I COULD NOT MAKE THE CORRECT CIRCUIT FOR THAT. CAN ANYONE PROVIDE ME THAT.
