DOSterm - A CTTY device for DOS machines, using a MessagePad. MS-DOS comes with a program called CTTY, which allows you to control a PC via the serial port. This Newton application is a terminal application that uses this feature. Plug the Newton into the serial port via a Null modem cable and enter the following commands into DOS,

MODE COM1:1200,N,8,1; CTTY COM1: this will set up the serial port for 1200 baud and switch input and output throught it. The Newton can then issue commands and display the results. Pure Novelty value. It does actually work and it is amazing to see a DOS directory listing in the Newton screen.
