I have been using the Rx interrupt with pic 16F88 several times without any problem since today.

The simple code below just go through ISR (Getbytes) only once after reset then no way to see the led_0 showup again, while Led_1 and Led_2 just work as they should.

Anybody sees where the error could possibly be?

Code:
INCLUDE "DT_INTS-14.bas"        ; Base Interrupt System
INCLUDE "ReEnterPBP.bas"        ; Include if using PBP interrupts

;wsave   VAR BYTE    $20     SYSTEM      ' location for W if in bank0
wsave   VAR BYTE    $70     SYSTEM      ' alternate save location for W 
                                         ' if using $70, comment wsave1-3

For A0 = 0 to 10

pause 500

next A0

goto MainLoop

Getbytes:

Led_0 = !Led_0

@ Return


MainLoop:

Hserin 1,TOut,[New_L]
if New_L > 0 then Led_1 = !Led_1
TOut:
A0=A0+1
if A0 = 1000 then 
Led_2 = !Led_2
A0 = 0
endif
goto MainLoop

end

Thank for the help.
