-* ----- --- -------  -----------------------------------------------
-* 1.01b jhl 5/13/02  First release
-* 1.01b jhl 10/14/02 Corrected bug in the receive function, the setup of the
-*		     interrupt status mask was not being done in the loop such
-*		     that a read would sometimes fail on the last byte because
-*		     the transmit error which should have been ignored was
-*		     being used.  This would leave an extra byte in the FIFO
-*		     and the bus throttled such that the next operation would
-*		     also fail.	 Also updated the receive function to not
-*		     disable the device after the last byte until after the
-*		     bus transitions to not busy which is more consistent
-*		     with the expected behavior.
