The Parallax simulator shows that a PIC16C84 will awaken from sleep by
an RTCC overflow interrupt that is triggered from the RA4/RTCC input
pin.

I have not found any documentation that confirms this, and cannot seem
to get it to occur on the actual chip.  I am attempting to awaken the
chip when a start bit from an RS232 serial input is detected.  The
serial input routine is interrupt driven from the RTCC and works fine
without the sleep instruction.

Can this be done ?
