Extremely useful DOS based serial I/O debug/diagnostic software. Can also be used as a simple data logger. ComShow displays all data received through a serial port so you can easily determine exactly what a device is transmitting. Unlike terminal programs, ComShow displays all characters that are received including carriage returns, linefeeds and all other control codes embedded in a serial data stream. ComShow also has output capabilities as well as the ability to manually set the states of all hardware handshaking lines.
