Ayamico, FYI, you could try writing a Cygwin wrapper program that would capture the output of a Windows process and print it out using Cygwin functions. This program should be able to recognize Cygwin ttys.
Search MSDN for STARTF_USESTDHANDLES, or see <http://msdn.microsoft.com/library/en-us/dncdev00/html/Remoteex.asp>, for examples of how to capture process output.
