Hello list, I'm new to the forums, but they have been very helpful!

Perhaps someone can help me with this snag... I'm using Hardware Serial Interrupts on a 18F452 reading in midi data. From the LED I have in the interrupt, I can tell the interrupt is operational, and I know that I'm reading the RCREG register because it clears the RCIF flag allowing main loop to run again.

Even though these two things are happening, the RCREG variable I'm putting into inByte is showing up as an empty value. Does anyone know why this could be happening? Code is below...

Code:
DEFINE OSC 20
DEFINE HSER_BAUD 31250

   On Interrupt Goto myint  ' Define interrupt handler (PBP  Gimme)  

   RCSTA =   $90            'didnt want to look up the binary for these ;)
   TXSTA =   $24
   INTCON =  %11000000      ' Enable peripheral interrupts
   PIE1.5 = 1               ' Enable Serial Interrupt

loop:  

LOW led
    'main loop
Goto loop        

' INTERRUPT HANDLER
Disable                         ' PBP Command - No interrupting past this point
    myint:                     ' If we get here, an interrupt has been thrown
       INTCON = 0              ' clear INTCON (maybe redundant)
       
       if PIR1.5 = 1 THEN      ' If Serial Interrupt (for mult interrupts)
          HIGH led
          inByte = RCREG       ' if this clears RCREG, then this will also
                               ' reset the PIR1.5 flag, therefore allowing
                               ' main loop to run again
       ENDIF
       INTCON = %11000000      ' Clear external interrupt flag

   Resume                      ' Glorified PBP "Return" to main program
Enable
