    en.wikipedia.org/wiki/USB-to-serial_adapter

    A USB-to-serial adapter or simply USB adapter is a type of protocol converter that is used for converting USB data signals to and from serial communications standards (serial ports). Most commonly the USB data signals are converted to either RS-232 , RS-485 , RS-422 , or TTL-level UART serial data.

    It sends data bits one by one, from the least significant to the most significant, framed by start and stop bits so that precise timing is handled by the communication channel. The electric signaling levels are handled by a driver circuit external to the UART. Common signal levels are RS-232, RS-485, and raw TTL [1] for short debugging links.

  4. Software flow control - Wikipedia

    en.wikipedia.org/wiki/Software_flow_control

    Hardware flow control, on the other hand, is typically under the direct control of the transmitting UART, which is able to cease transmission immediately, without the intervention of higher levels. To handle the latency caused by builtin FIFOs , more advanced UARTs, like the 16950, provide "on-chip" software flow control. [ 1 ]

    The USART's synchronous capabilities were primarily intended to support synchronous protocols like IBM's synchronous transmit-receive (STR), binary synchronous communications (BSC), synchronous data link control (SDLC), and the ISO-standard high-level data link control (HDLC) synchronous link-layer protocols, which were used with synchronous voice-frequency modems.
