Termite

Termite is a simple RS232 terminal, which uses an interface similar to that of "messenger" or "chat" programs.

It comes with a large window that displays all received data and an edit line for typing in strings to transmit. Unlike other tools, it uses a heuristic search for selecting an appropriate COM port. Termite also allows you to select non-standard Baud rates (MIDI, DMX512). Termite focuses on text data, and specifically text that is sent and received as strings terminated with "new-line" characters. It has no provisions for transferring files or binary data.
