Yeah, though buffering isn't the problem here. It's that the password
is rendered in the clear as you type it by the Windows FTP client if
you run it from a Cygwin terminal. This is why I suggested *not*
running it from a Cygwin terminal if Mike really wants the Windows
FTP client. Whether the Windows FTP client is run in a console or
cmd.exe is really, in this case, inconsequential. Both will work
for the work-flow Mike describes. The key take-away from the original
post is that the Windows FTP client is being used, not the Cygwin one.
That's why I mentioned using the Cygwin one as another alternative to
avoid the observed behavior of the Windows FTP client with Cygwin
