You can use tnsping to "ping" the listener, or something else that occupies the port (with various results), but it will not tell you if a service/sid is available or not on that listener.
C:\>tnsping (description=(address=(protocol=tcp)(host=localhost)(port=1521))
(connect_data=(sid=nothing_here))) 3
