Problems with PIC 18F4620 program in CCS C Compiler

[brn.caldeira]

Hello,

I´m starting programming in C and I have a problem with my code.When I press a key in PC the program points to the begin and does not recognize the characters written.I´m using CCS C Compiler.

#include <18F4620.H> // arquivo de definições do microcontrolador usado
#use delay(clock=10000000) // informa ao sistema o frequência de clock, para temporização
#use rs232(baud=9600,parity=N,xmit=pin_c6,rcv=pin_c7)
#fuses HS,NOFCMEN,NOIESO,PUT,BROWNOUT,BORV43,NOWDT,CCP2C1,NOPBADEN,MCLR,STVREN,NOLVP,NOXINST, NODEBUG, PROTECT,CPB,NOCPD,NOWRT,WRTC,WRTB,NOWRTD,NOEBTR,NOEBTRB

#bit TX_TTL = PORTC.6 // 0 reservado Out
#bit RX_TTL = PORTC.7 // 0 reservado Out

// *** Rotina Principal
void main(void){
unsigned char caract;
int data;

printf("working");

for (;{
switch(getc()){
case '1': printf("potência");
break;
case '2' : printf("temperatura");
break;

}
}
}


someone help me?
