Can someone tell me if I am going in the right direction?

Okay, when the pin is not connected at all, it gives the expected two lights flashing like SkiMasks code defined. But with the pin is in, it does nothing.

PIN ? What pin? the serial connection? try a 10k pullup on that line.

[MatthewM]

Yes, the serial connection, if I disconnect it, the two lights flash, otherwise nothing happens if it is plugged in.

HS OSC setting provides more electrical power to the OSC than XT setting does, sometimes it is possible to have XT work intermittently for 20, not reliable though.

add this to your code:
ADCON0=0

[MatthewM]

What do you mean?

Also, I tried the 10k pullup, no effect. Still goes dark with the jumper is connecting the pins.

Matt, do you have the 2 LABX boards hooked to a common power supply? You should have a common ground between them. ADCON0=0 disables A/D too

[MatthewM]

Yes, I have a common ground. What do I want for my ADCON settings?

Right now I am using the codes that where given to me by skimask, unchanged.

Well guys, thanks again for your time, it's unimaginably nice to have people to ask questions, instead of manuals...Lol. But I need to sleep, I have a rather large amount of family events to contend with tomorrow, so I need to turn in. Hopefully sleeping on it will give me an idea.

Alright...time to completely forget ALL about this serial business...
TX Side:

DEFINE OSC 20                   'Defines oscillator rate
ADCON1=$ff : Output PortD.0 'output on PortD.0
LOOP: PortD.0 = 1 : pause 500 : PortD.0 = 0 : pause 500 : goto loop
END

Should flash an LED connected to PortD.0 once per second, 1/2 on, 1/2 off...

RX Side:

DEFINE OSC 20
temp var byte : Input PortB.7
Loop:
if PortB.7 = 1 then 'checks logic level on Portb.7
PortB.0 = 1 'if it's high, set B.0 high
else
PortB.0 = 0 'otherwise set it low
endif
temp = temp + 1 : portB.1 = temp.7 'increase the temp variable, and set b.1 to match the temp variable's bit 7
goto loop
END

PortD.0 on the TX, connected to PortB.7 on the RX.
LED connected to PortB.0 <- follows PortB.7, which should follow PortB.7
LED connected to PortB.1 <- should flash quickly showing that the loop is running...if you think it's flashing too fast to see it, change temp var byte to temp var word and change temp = temp + 1 : portb.1 = temp.7 to temp = temp + 1 : portb.1 = temp.15

If that doesn't work, you've got hardware and/or config problems somewhere and it's time to write a blinky for both individually and get the pins themselves working.

ADCON0 and ADCON1 are 2 seperate registers, do different things, related to A/D converters
ADCON0 = 0 shuts off A/D
ADCON1 = $FF? i would set as ADCON1 = 6 or 7 , data sheet chart shows all digital with those settings, no VREFs . . .
