What is the correct procedure for setting the key board LED's?

I have looked at the key board handler in ALLEGO however there is little
or no explanation as to what exactly is being done.

Which port do you need to write to? I tried writting to 0x60 and 0x64 but
nothing happened.

What is the structure of the flag you must send to the key board? Is it
the same as or similar to the DOS state shift key flag?

Is it absolutely necessary to wait for acknowledgment from the key board
after writing to it?

Do you just write the flag to the key board port or do you have to send a
function code first followed by the flag?
