Rentron's TX-IR PIC Needed / Pre-programmed PIC12F609

[prodabbler]

Anyone have this pre-programmed part that I can purchase? Seems Rentron is no longer, but if the program can be obtained that would be nice as well. We purchased them with the IR program in them, hence the TX-IR part name. Thanks in advance!

I'm in a serious bind. Is the original code for the Rentron's TX-IR PIC obtainable? I need the 38kHz PWM code (50%) duty cycle. I'm using an external 4MHz oscillator. I can not seem to duplicate it since I'm still trying to interface to an emulator to debug. I've simply run out of time. Any help would be greatly appreciated! Below is what I think it is.

----------------

PROCESSOR p12f609
#include "p12f609.inc"
__CONFIG _MCLRE_OFF & _CP_OFF & _WDT_OFF & _XT_OSC
#DEFINE PORT B'11111101'
MOVF OSCCAL
MOVLW PORT
TRIS GPIO

END

Followed by your code should work
