Serin2 - All I Need Is 8 Numbers....

[SOMRU]

I know the answer is right in front of me, if someone could please direct me.

This is only a small part of a larger project of 8 pics in all. This stage requires me to adjust and communicate two four digit numbers across serial lines. I have read, sturred, thought, and am now totally confused.

I am using two 16f870 ref'ed as PIC6 & PIC7.

Here is the code as follows

PIC6 RECIVER / DISPLAY CODE
