Serout2/serin2 Pbp Problem

GREETINGS ALL!!
AS USUAL I'M IN SEARCH OF THE OBVIOUS.
I'M USING 2 PIC16F870'S AND PBP.
IT CAN NOT BE THIS DIFFICULT TO TRANSFER A FOUR DIGIT NO. ie 1234
FROM ONE PIC TO ANOTHER WITH ALL THE MAGIC PBP HAS.
I SEEM TO BE MISSING THE INCANTATION, AND AM ASKING IF SOMEONE
COULD RECITE IT FOR ME. FOLLOWING IS THE CODE.

Hi, now calm down and please stop shouting :)
look at the red highlights, I cannot find 84 as valid for serout2 - serin2 yes. if you are trying to send at 9600 baud then why receive at 1200 baud?

In the above chunk, you Gosub SND6, the subroutine returns from it, and then you enter SND6, AND it RETURNS...to...nothing. Unless you've got some other code in there somewhere that you took out for brevity, it looks like you've got one of those deals where you're returning without GoSub'ing. That tends to send the PIC into la'la land. Check it out...
