DT_INT + 16F72 - what am I missing?

[Megahertz]

What is your hardware? I mean how is the controller connected to the PC?

How are you sending the serial data stream?

I have an RF receiver attached to the unit. I even tried to remove the receiver and connect both PICs hard wired. Still no response.
By the way, just to confirm that for the 16F72 do I need to connect 100nF anywhere else as well, I have one already connected to pin 19/20. Vss is supplied to pin 19 & 8, Vdd goes to pin20 only.
