16F877a to PC to Handphone

[E11022]

i do not have GSM module and the serial cable DRS-11 for Sony Ericson T630 . Hence i need to use PC for the serial port, then to Handphone. yup, can Hyperterminal handle 2 com ports? this is another doubt.
if i only wanna display output to PC?

My PC got COM port, so i connected it like this:
Pin 2 (RS232) - Pin 14 (MAx232)
Pin 3 (RS232) - Pin 13 (MAX232)
Pin 12 (MAX 232) - Pin 25 (PIC)
Pin 13 (Max232 - Pin 26(PIC)

I think there's something wrong with the connections to MAX232. Please check it carefully refering to the datasheets of max232.

typo mistake.i manage to display data from PIC to hyperterminal,using putc('A'). but when the same command is add in my program code, the circuit is not working. I asked my friends about it. We debug the code together, cannot find any problem on the code.
#include "16f877a.h"
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=20000000)
#use rs232(baud=9600,xmit=PIN_C6,rcv=PIN_C7)

#define sensor PIN_A0
#define sw PIN_A1
#define buzzer PIN_C5
#define led PIN_C4


void main (void)
{
set_TRIS_C(0x00);
set_TRIS_A(0xff);

while(1)
{
if((input(PIN_A0))&&(!input(PIN_A1)))
{
delay_ms(100);
if((input(PIN_A0))&&(!input(PIN_A1)))
{
puts("help!");
output_high(led);
output_high(buzzer);
}
else {}
}
else if ((!input(PIN_A0))&&(input(PIN_A1)))
{
output_low(led);
output_low(buzzer); }
else {
output_low(led);
output_low(buzzer); }
}
}
