Given that sqlplus is a native Windows application as opposed to a
Cygwin application, there is no way to do what you need directly under
Mintty.  The problem is that Mintty uses ptys for its console handling,
but Windows applications don't know about such Cygwin constructs.  All
they see is a pipe, so they can't do things like disabling console
echoing as they would when they have a real Windows console in which to run.

The only way to make this work with sqlplus if you want to primarily use
Mintty as your terminal is to spawn a cmd window for sqlplus to run in:

cygstart "$(which sqlplus)" risingp1 AT CTIBETA2

I think that should work for you, but I haven't tested it.
