Hi,

It seems strange to me that if I do "ls -l /dev/tty" on a standard
configuration I see details for a file, but if I do "ls -l /dev"
it's not there. I  thought it might be nice to have a real /dev
directory with real entries, so I tried to add some. Using the
cygwin file utilities I can make the /dev directory. but I can't
make the files because the "devices" already exist. However, if I
use windows utilities I can make the files. I have now got to the
point where I can so the following:

Administrator AT JOHNS-2ND-STAR ~
$ cd /dev

Administrator AT JOHNS-2ND-STAR /dev
$ ls -l
total 0

This is OK as far as it goes, but I'd like to have a complete list
of the device files supported. There seem to be several (inconsistent)
sets of file names in the cygwin dll if my reading of the source code
is right (but it may well not be!)

Can anyone provide an exhaustive list of the "devices" available
in the /dev directory ??

I'd also like to suggest as a complement to the "mkpasswd" and
"mkgroup" utilities, a "mkdevs" utility that created the /dev
directory and the device files in it - does anyone else think
that would be useful ?

Thanks
/John Vincent.
