If that's the case, simply remove that section, and it should work much better.

Looking thru the ASM generated by PBP, I could not find anything related to the PCLATH. Here is what I have working with the Help of MELabs of course (Thanks Mr. Leo!):

Code:
        
        Adcon1 = 6 'disable analog comparator
        TRISA = %11111111 'Set Port A to inputs

        pir1.5 = 0 ' clearing interrupt flags
        Mess Var Byte
'____________________Main_____________________
 
Start:

PicRecieve:      
      If PIR1.5 = 1 then Pic_serin
      Goto PicRecieve
 
      Pic_serin:
      Hserin [Mess]

IncomingM:
        If Mess= %00000001 Then mess1
        If mess= %00000010 Then mess2
I am using MPasm to assemble the PBP code. The only thing I see related to the inerupt in the ASM is here:

How long a cable do you think I can get away with? I am trying to evolving this into a paging system (functional learning project) and was thinking of using 100' of Telephone wire. Too far? Or would it be better to use a twisted pair like the Cat5 wire?

Thanks Darrel
