Help needed - PIC12F635- MCU does not read Ports

[financecatalyst]

I have tried almost everything, nothing worked untill now. BUT when I remove the serial input line from this code, it works well as expected manually. Could someone please tell me how I can use both features in this command?
Thanks

Add a time out to the serial command. If a signal is not received then the code will not get stuck waiting for a serial command.

Did that and it works - BUT- now when I power up the circuit, my gpio.5 goes high after 1-2 seconds even though I haven't send any signal.
Any solutions?
Thanks

Do you have gpio.0=1 pulled down with a 10K resistor?

NO, do I have to?
I am new in this field, I may sound silly but I have not used any resistor on any pins, they are connected directly to leds. What does this resistor do?

I was not meaning the pins with LEDs.

It sounds like you have gpio.0 connected to a switch of some kind.
When the switch is pressed the pin goes HIGH.
A pull down, resistor to ground(zero rail) will keep the pin LOW, not allowing false signals until the switch is pressed forcing the pin HIGH.

Thank you very much. This problem is solved.
