I have now updated the shar and patch to uart(4) code from head (instead of 9.0), fixed read() not respecting O_NONBLOCK, and improved behaviour at kldunload: http://people.freebsd.org/~nox/tmp/uart-lirc-preliminary-002.patch and http://people.freebsd.org/~nox/tmp/uartlirc-preliminary-002.shar If someone would like to comment on the code I'd be grateful! :) On Tue, Apr 24, 2012 at 11:08:38PM +0200, Juergen Lock wrote: > Hi! > > For those that don't read forums.freebsd.org: I posted a short review > of "FreeBSD Device Drivers: A Guide for the Intrepid" by Joseph Kong, > > http://forums.freebsd.org/showthread.php?p=175029 > > and wrote a serial lirc driver in the process.
