Newton keyboard driver
|
From: Justin C. <jp...@do...> - 2001-01-14 17:49:00

ok, here's a ruby patch to add a Newton keyboard driver. It is a nice
portable serial keyboard that Apple sold may years back. If noone has
any suggestions for changes I'll submit it to 2.4 as well. The only
thing about 2.4 is that serio.c is in drivers/char/joystick and this
will go into drivers/char: serio really ought to move to char, as it is
not joystick specific.
