Are you having a problem?  If so, please follow the instructions at
http://cygwin.com/problems.html.

I only know of the following two issues:
1.) tcflush can hang for a while if the device constantly streams data.
2.) Communications can cease if the device overflows the input buffer.

1.) was fixed in CVS on 2003-12-11.  Any snapshot after that will include
it.  Otherwise, it will be in Cygwin 1.5.6 when it is released.
2.) I have a partial fix for, but since it doesn't directly effect me, I
have not given it any priority.
