Here's the latest code, doesn't work though

Is it ok to leave the PIC - pc cable unplugged? If not where should it go?

The PIC is a 16F684

 ANSEL   = %00000000    'Disable analog select so ports work as digital i/o.
CMCON0  = %00000111    'Disable analog comparators.
TRISA   = %00000000    'Set PORTA as OUTPUT.
PORTA   = %00000000    'Set PORTA pins all low.
TRISC   = %00000000    'Set PORTC as OUTPUT.
PORTC   = %00000000    'Set PORTC pins all low.

MYVAR  VAR BYTE 
 
MAIN:
PAUSE 250
SERIN2 PORTA.0, 16780, [DEC MYVAR] '2400 INVERTED
IF MYVAR = 3 THEN HIGH PORTA.5
PAUSE 250
GOTO MAIN
