NAME
     ustir -- SigmaTel STIr4200-based USB-IrDA bridge support

SYNOPSIS
     ustir*   at uhub?
     irframe* at ustir?

DESCRIPTION
     The ustir driver provides support for USB-IrDA bridges based on the SigmaTel STIr4200.  The
     driver is known to work with the following adapters:

	   Mars II 740 USB IrDA Adapter

     Access to the IrDA device is through the irframe(4) driver.

SEE ALSO
     irframe(4), uirda(4), usb(4)

HISTORY
     The ustir driver appeared in NetBSD 1.6.

AUTHORS
     The ustir driver was written by David Sainty <David.Sainty@dtsp.co.nz>.

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