USB TTL Serial Cables The USB TTL Serial cables are a range of USB to serial converter cables which provide connectivity between USB and serial UART interfaces. A range of cables are available offering connectivity at 5V, 3.3V or user specified signal levels with various connector interfaces. Other related homebrewing: I bought a programming cable for my Yaesu FT-817ND and got a cable made for “RT Systems”, a company that distributes control software for different radios like this. I did not buy that software and expected the cable to show up as a USB serial port on my Linux machine.
