It's possible that you are accustomed to using, or using a script
written for, the 'nc' command that was included in the 'netcat'
package, which was superceded in Cygwin some years ago. This could
have happened if you were using Cygwin 1.7 (I think) and then upgraded
to a brand new version of Cygwin. It is common, in my experience, that
someone would have installed an old version of Cygwin, used it for
years, and then upgraded to a new version.
