Q: sun serial keyboard on x86 system?

[Ralf A. <ra...@KO...>]

Hello,

i try using a serial sun5 keyboard on an x86 system.
I've used the adapter described at the "Linux Input Project" site - and
can see characters arriving on keypress / release when using e.g. minicom
on the serial port the keyboard is attached to.

Unfortunately i fail to get the keyboard itself working
I'm using Linux 2.4.1.
I do an
	insmod .../serial.o
	insmod .../serio.o
	insmod .../serport.o

	inputattach -skb /dev/ttyS0 &

	insmod .../input.o
	insmod .../evdev.o
	insmod .../keybdev.o

but apart from an entry
	Mar 27 23:01:16 dell kernel: serio0: Serial port tts/0
in /var/log/messages i don't get any further reaction.

Is there something special that i miss? Do i have to create any special
devices in /dev/... ?
How to debug the whole process? Is evtest usefull for that - or does it
primarly deal with joystick devices / mice?

Any hints will be highly appreciated - i'm just doing a version of an
PS/2-to-serial adapter for attaching PS/2 (chording) keyboards (like the
Handykey Twiddler2 http://www.handykey.com) to a Compaq iPAQ PDA running
Linux - but testing / developing with the serial Sun5 keyboard on an x86
system makes development much easier.

Best regards
