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

All input devices can be accessed threw /dev/input/eventX. Take a look at
dmesg. You should see all your /dev/eventX devices registered. Do this
after you run inputattach. For example I have a serial mouse. I do a
inputattach -ms /dev/ttyS1. Then reading dmesg I see a message similar to:

input3: Serial Mouse on serio0
event3: Event device for input3

Now you know everything is working :-) Now to test it ...

.. with evtest. Every input device, keyboard, mouse, touchscreen etc has a
/dev/input/eventX associated with it. Just run evtest on the proper
/dev/input/eventX and you will see it work. Test it with that device. For
2.4.X the events of the keyboard should to to the console. With this
versus all keyboard events go to the console system. In the CVS tree we
have. The keyboards are attached to a specific VT. If you make 3 keyboards
and 3 video cards they will all behave as a seperate terminal independent
of each other. Data from one keybaord will not end up on another
workstation.

Many thanks,

just getting sunkbd.c from the CVS and loading the compiled module worked
perfectly!!

Evtest will work once the device is found. You're still missing the most
important driver of the stack.
