This is nothing the C or C++ language provies.

If you want a solution using Linux you can try to get the ioperm() for
the keyboard controller register and send stuff directly - don't know
how that will interfere with the kernel keyboard handling routines, however.

There are no such things as ps/2 keyboards in c or c++

What is an .EXE file in linux???

using c or c++ in linux os how can i do?

HINTS:
1) post to correct news group
2) use the device driver for your special keyboard, or write your own
device driver and use it

extension but is executable.

1) post to correct news group

inst this the right one? maybe comp.lang.c is better?

2) use the device driver for your special keyboard, or write your own
device driver and use it

the keboard doesnt have a driver.

thanks Johannes Bauer , now i look for that ioperm().

No, somewhere like comp.os.linux.* would be better.

Look at the Documentation/input directory in your Linux kernel source
tree. I think that you need to write to /dev/input/something.

There is a linux-input mailing list,
(e-mail address removed), which would be the best place to
ask about this.

Too late, he posted it over in CLC.

As Erik suggested something with Linux

the keboard doesnt have a driver.

Write one. It needs to access something in
/sys/bus/...
or
/sys/devices/...
I never did it, so have no idea

thanks Johannes Bauer , now i look for that ioperm().

Who is Johannes Bauer??

BTW this is from ioperm() man pages:
1) The use of ioperm() requires root privileges.
2) This call is mostly for the i386 architecture. On many other
architectures it does not exist or will always return an error.
