Sorry about that.

I'm not actually...

I am trying to figure out how a serio driver actually gets "hooked" to a
serial port. The i2c-taos-evm driver looked simple enough to play with
in order to figure it out. I was trying to follow the Documentation in
order to use it and ran into the issue below.

Yeah. I did a bit of searching yesterday and it appears the user space
tools development went stale around the end of the 2.4 - start of the 2.6

That helps. Thanks.

Do you know if there is a way to make the connection in kernel?

Also, do you know if there is any information on the serio stuff
available anywhere? Other than just reading the kernel source I
have not been able to locate anything.

Thanks for the reply,
