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

|
Access to the IrDA device is through the
|
|
.Xr irframe 4
|
|
driver.

|
.Sh HISTORY
|
|
The
|
|
.Nm
|
|
driver
|
|
appeared in
|
|
.Nx 1.6 .
|
|
.Sh AUTHORS
|
|
The
|
|
.Nm
|
|
driver was written by
|
|
.An David Sainty Aq David.Sainty@dtsp.co.nz .
|
|
.Sh 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 performance is not overly
|
|
affected by rapid polling, but latency is fairly high.
