Re: Raw IR read/write with Actisys 220L+

Hi,

If you're comfortable looking at the kernel drivers, maybe take a look
at sirdev_raw_read and sirdev_raw_write (and nearby) in 
drivers/net/irda/sir_dev.c

I doubt that the hooks there were at all intended for what you are
trying to do, but the calls are at least aware of the rest of the stack,
while still allowing raw reads and writes. (This may not work without
modification, but I suspect it would be the best place to start if you want to
coexist with the irda stack, or at least use the hardware drivers)

Most of what the actisys dongle driver itself (actisys-sir.c) does is just to
reset the dongle, bring it up into a known state, and then set the
line speed. If you really want to avoid the irda stack altogether,
it should be trivial to do this in userspace and avoid having to write
a totally new kernel driver.
