TTL, or Transistor-Transistor Logic, hardware protocol is a low, non-differential voltage version of RS-232 protocol. Typically, a voltage of 5V or 3.3V is used for high logic, while low logic is 0V. These lower voltages favour embedded applications, but make the protocol less robust to noise. As a result, TTL applications are typically implemented over shorter distances than RS-232.
