Sorry folks if you had been getting mails bounced.
I had enough of spam. On average 5 to 10 spam per day comming
the idiots colecting my e-mail addresses from mailing lists.
Although i had over 200 IPblocks banned at the router level, still
some of the spammers were getting through.  Majority of the spammers
seems to have accounts at and, so and IP Netblocks had been completely banned.

Sorry about the bounced messages.  Please send messages through
cygwin and cygwin-xfree list if your message bounced... it means
your IP block belongs to an ISP from whom I received repeated junk

To answer your questions, you are absolutely on the right track.
The devices must be accessed via Win32, but X will run on Cygwin.
The only /dev/xxx X will need from Cygwin is /dev/conin (/dev/tty)
which is needed for xterm, xinit and xdm etc.  Accessing hardware
memory via
Cygwin will slowdown X to unacceptable level and may cause problems.
The example driver for OS/2 from Holger is a very nice hack which he
wrote to offer /dev/mem and /dev/io which are missing on Windows and

After you have looked at the source code and you have your
suggestions, we could discuss and plan on how to do it.
Your help will be highly appreciated.
