HISTORY

     The ustir driver appeared in NetBSD 1.6.


AUTHORS

     The ustir driver was written by David Sainty <dsainty@NetBSD.org>.


BUGS

     The STIr4200 cannot notify the driver when it has received data, instead
     it has to be continuously polled.  This driver polls (when idle) at a
     fairly low rate of 10 times per second, which means that system perfor-
     mance is not overly affected by rapid polling, but latency is fairly
     high.
