How to off automatic detection of non-U.S. keyboard configurations?

[David Komanek]

Hi all,

please, is there any way to switch back to us-keyborad mapping on the 
non-us WinXP ? It seems there is an automatic detection of  non-U.S. 
keyboard configurations in Cygwin XFree (4.2.0, downloaded and installed 
today) and I have no idea how to switch it off. I didn't find an answer 
neither in maillist archives nor XFree faq. Or is there at least a way 
to pass charactesr via ASCII codes to the xterm window ?

Thanks in advance,

 David Komanek
