Rc signal help

[geckogrotto]

I have read quite a bit on this and most sources point to using PulsIn.

I found some code on the web for another chip and am trying to modify it for 12F675 but am getting no love.

'12F675
@ __CONFIG _INTRC_OSC_CLKOUT & _WDT_OFF & _MCLRE_OFF & _CP_OFF
OPTION_REG.5 = 0                                                       ' clock source internal

Pulselen   var Byte                                                 ' Pulselen can be 0 - 255, 100 = 1 ms, 200 = 2 ms
Init       var Byte                                                 ' Init used to flash LED
Clear                                                                  ' set all variables = 0

Input GPIO.3                                                           ' set pin 5 to RX signal

ReadPWM:
   PulsIn GPIO.3, 1,Pulselen                 ' pin 4 - read high pulse length, times out after .65535 seconds 
   pause 15                   
   If Pulselen < 50 Then GoTo Blink           ' no signal  -> blink led
   If Pulselen > 50 Then GoTo Solid           ' signal  -> Solid led
   GoTo ReadPWM               
        
Blink: 
   For Init = 1 To 3                                                   ' blink led 3 times
      High GPIO.1                                                      
      pause 200                                                      
      Low GPIO.1                                                     
      pause 200                                                      
   Next
pause 1000		    
 GoTo ReadPWM 
 
Solid: 
      High GPIO.1                                                      
      pause 3000                                                      
      Low GPIO.1
      pause 200
 GoTo ReadPWM

It should blink when no signal and be solid when there is but it seems to do whatever it wants no matter what signal I try and send it.

Is it the config settings?
