This probably belongs on the main cygwin list (cygwin @ cygwin.com)
because it doesn't seem to have anything to do with X11.

I have had this happen before, and I believe it's because windows'
native ftp program is confused by ptys (which are implemented with pipes
internally.)  Many native win32 programs react in strange ways if their
input/output is attached to a pty, which will be the case if you're
running in a rxvt/xterm window or a regular bash command prompt with
'tty' set in your $CYGWIN.

The solution is simple, install the inetutils package which includes
among other things, a cygwin version of telnet that knows about ptys.
