Newton 2.0 OS: Serial 9600 Package Explained

When I tap on the Serial 9600 icon in the Newton 2.0 OS Extras Drawer, a message appears that reads: "Packages: Tapping this does nothing." I looked for a reference to the Serial 9600 package, but couldn't find anything. What does this package do?
The Serial 9600 package is only used when communicating with older Windows-based computers. The Serial 9600 package is a standard package that is loaded at the factory. It adds one item to the "Connection" popup (Windows - 9600). Allowing Windows users to reduce the serial speed to 9600 bps. This option was added because some older Windows-based computers cannot communicate at 38.4 Kbps.
