Serial Terminal App to program Cisco Routers

Does anyone know of a good app to access Cisco routers via the serial port?
I have a Belkin USB to Serial adapter, so I guess the app should also have drivers for it.
In Windows / DOS there used to be tons of those, then only HyperTerminal (which I've been using with Parallels). But I one a native Mac app for this purpose.

The other choice is use my iPad, but it would require me to buy a $60+ cable, which who knows for how long it will be supported.

Thanks in advance for your feedback
