Termite is an easy-to-use and easy-to-configure RS232 terminal. It uses an interface similar to that of "messenger" or "chat" programs, with a large window that contains all received data and an edit line for typing in strings to transmit. Highlights of the utility are the ease of installation (possibly with pre-configured settings) using a heuristic search for the appropriate COM port and, as mentioned, its user-friendliness.
Most RS232 settings for a device can be chosen by the developer (the Baud rate and the number of data and stop bits are usually determined by the other device). One setting that the developer cannot foresee, however, is what COM port the user will attach it to. For this reason, Termite contains a "port lookup" function plus a simple "port scanning" protocol.
