Nifty.

Please do send me a copy should you get it together, and preferably
the list as well -- it sounds like the modifications needed to use it
over my existing version should be slight, and the benefits
significant; I'd be happy to see it (or any such solution) included in
the tree.

Please do. I like to see this as well. Sounds pretty cool.

I did something similar at
http://www.iptel-now.de/HOWTO/INPUT_DECOMPOSED/input_decomposed.html
It's using a new device though (the same way Alessandro Rubini did in his
example and the other email this week did. BTW - i was unsure whether
this approach can handle bytes arriving "byte by byte" and not "on
block", so i used another "re-assembling" algorithm, the (hardware)
devices that i use to inject the events do send interleaved anyway).

I like the idea of just "inputattaching" to a pty much more too though !
So looking forward to having a look at your code.

Your the PS/2 to serial guy. BTW where can you pick up one of these
devices? I like to order on to show it off at the company.

Ah. I really need to write some docs on input driver writing. We have docs
but they could be better.

Me too. I look forward to Justin's code. Does this mean we can send events
from a remote machine?

That's what I'm doing with my existing code (posted earlier); Justin's
should allow it also. (I'm also involving some userland pipes to do
byteorder adjustments and such, but these shouldn't be necessary in
most cases).

Hum. I thought it was a work around for hotplug as well as for testing to
inject event packets into the input core. I didn't realize you could do it
remotely as well. Actually I just realized you could make these event
occur over the network.

I see everyone is working for the same thing. I hope everyone can merge
their work together.

Hello James,

I made the existing ones on my own. I can send you one handwired
prototype (i have made 2 and don't need them both at the moment. It does
the keyboard conversion only, the mouse part is soldered and wired but the
ATMEL software (for interleaving, mouse alone works too) is not fully
finished yet) for testing. I leave for 3 weeks of conferences and
holiday next Monday, so just drop me a note and i'll send it by air mail.
I benefit a lot from what the linux-console people did, so that's ok.
