Serial port monitor

I am looking for away to view and capture data from the serial monitor in arduino. I would like to save it to a file. Someone suggested a sereial emulator, but no name. What program would I need to do this? Arduino serial monitor fonts are too small and I have lost the window to stop the scroll.
Thanks

You haven't said what operating system you are using.

For Windows, MacOSX or Linux?

On Linux, you can simply "cat /dev/whatever > filename" from the command line. I imagine this works on MacOSX, too.
On Windows, it used to ship with a program called HyperTerminal, but I don't think it does anymore. However, the free program "putty" can open a serial port, and it can also log all data on a connection to a file, for example.

WINDOWS 7 AND xp

Hyperterminal is included with windows XP.

realterm has a logging function
