Eltima Serial Port Terminal - a handy application for testing serial ports.

The main purpose of Eltima Serial Port Terminal is to establish connection to serial port and send/receive various types of data down the serial line. Eltima Serial Port Terminal is a session-based, multi-purpose application that provides simple communication interface to connect to any serial port device (modem/fax/GPS/mouse/printer and so on). Eltima Serial Port Terminal allows you to open as many serial ports as you like (including virtual serial ports); dynamically change serial port settings without necessity to close and reopen current port; adjust baudrate, databits, parity, stop bits, flow control parameters; save all received bytes into a file for later analysis and lots more. Being a session-based, Eltima Serial Port Terminal allows creation of options set and saving them under individual session names for different hosts. Unlike other terminals you may not only send, but also receive and view data in hexadecimal format, switch between dump and terminal view modes, etc, which could be very useful for debugging and testing serial port connections.
