Sscom 3.2 is a compact Windows application that allows users to open a COM port, set baud rate, data bits, parity, and stop bits, then send and receive data in ASCII, hexadecimal, or string formats. Its particular strengths are support for high baud rates (up to several Mbps), automatic sending of data frames, file transmission, and a straightforward log function. Unlike terminal emulators focused on human interaction (e.g., HyperTerminal), Sscom is designed for device testing — sending specific command bytes to a microcontroller and viewing raw responses.

These provide similar or superior functionality without the need to hunt for an obscure 3.2 binary. Under the "Extras" menu, set an automatic response
