A serial device is a device that provides serial communication interfaces, also known as serial ports. Through serial ports, information transfers in or out sequentially one bit at a time. While interfaces such as Ethernet, FireWire, and USB also send data as a serial stream, the term serial port usually means hardware compliance such as RS-232, RS-485, or RS-422.
Examples of serial devices are microcontrollers, printers, modem, and specialty mice. Read the Chrome Enterprise Policy for Serial devices.
