I don't know. I've never tried to do anything with it.

As I understand it /dev/conout is the same as the Windows CONOUT$
device. As such it's Windows stdout, as per se. As a Windows stdout, it
doesn't know anything about Cygwin's POSIX implementation of ptys. So,
in a Cygwin Windows Window (i.e. the same window that you get when you
do a cmd window in Windows) output to /dev/conout should show up just
find in Cygwin's stdout. Therefore a cleartool ci <file> should prompt
you for a checkin comment.
However, if you used ptys then the output to /dev/conout, and thus to
Cygwin's stdout, will not show up because, again, Windows CONOUT$ does
not understand ptys. How/Why do you use ptys in Cygwin? Various ways.
For example, if you use xterm or rxvt, you'll be using ptys. This sucks
because I like rxvt much better than the cruddy Windows window and rxvt
doesn't incur the overhead of an X server - it can work without it.
How else do you start using ptys? Well if you ssh to a machine, again,
you'll be using ptys.
So I've always just used something like "cleartool ci -c 'my comment'
<file>" or "cleartool ci -nc <file>" and if I ever do a cleartool
command and it seems to hang the first thing I think of is "Oh I bet
it's that pty thing".
There is another terminal emulator software called "terminal" I think,
that runs on Windows and interacts well with Cygwin. It also allows you
to do gnome-terminal like things like transparent backgrounds. IIRC it
seems to run a cmd window in the background and handles this issue with
cleartool (and, BTW cqperl's debugger) properly - well sorta properly.
I'm sorry I don't have a better reference for that terminal emulator. I
used it at my last client. I have IM'ed a friend to ask him where he
found it. I'll report back if I get a good reference.
