Serial problem between BasicStamp code and PBP code

[Archangel]

No "NIBs" in pbp only bits, bytes, words & longs. Are you using "Default" configs ? have you gotten an LED to blink? I see NO "DEFINE OSC 4" in your code to tell PBP the pic is operating at 4 mhz
Are you using a crystal, a resonator or internal RC oscillator? Does you config statement reflect what you actually have ?

I have tried changing serial config from true to inverted the manual also says bit 15 can be for open or driven. Whatever that means.

open is an open collector where a pullup resistor pulls the output high whereas driven means an output transistor drives the output high or low.
