16f88 Pin 9 (CCP1) tied high locks up PIC

[bownes]

I have a simple F88 circuit. Pin 9 has a 10k pullup on it. When I connect this pin, the PIC locks up. When I let it float, my code runs fine.

Using RS232 on RA2 and RA3.

I'm pretty sure the problem is in the initialization and set up code, but it isn't clear how to disable CCP1

Clues?

Code:
void main()
{
unsigned char c, cmd[15],command;
int i,x,y = 0;

setup_adc_ports(NO_ANALOGS|VSS_VDD);
setup_adc(ADC_OFF);
setup_ccp1(FALSE);
setup_spi(FALSE);
setup_timer_0(RTCC_INTERNAL|RTCC_DIV_1);
setup_timer_1(T1_DISABLED);
setup_timer_2(T2_DISABLED,0,1);
setup_comparator(NC_NC_NC_NC);
setup_vref(FALSE);
setup_oscillator(False);
set_tris_b(0x00);
set_tris_a(0x0f);

while(1){
puts("CMD: ");

i=0;
c = getchar();
cmd[i] = c;

while ( c != CRLF ) { // read a command string
i++;
if(i == 20)
i=0;
c = getchar();
cmd[i] = c;
}


if (i>20) {
i=0;
puts("Error\n\r");
} else {
command=cmd[0];
switch (command)
{
case 's': // set a relay
x=(cmd[1]-'0');
printf("setting %d %c\n",x,cmd[1]);
set_relay(x);
puts("Set!\n\r");
break;
case 'c': // clear a relay
clear_relay(cmd[1]-'0');
puts("Clear!\n\r");
break;
case 'a': // clear all relays
clear_all_relays();
puts("Clear all\n\r");
break;
case 'l': // set all relays
set_all_relays();
break;
default: i=0;
break;
}
}
}
}
