A serial line is a means of transmitting data in bit serial fashion, often over a communication link such as a telephone line. There are two principal forms:

  • asynchronous serial lines, in which the format is self-clocking (i.e. the start location of each character can be inferred from the data stream), and
  • synchronous serial lines, where each character starts immediately after the previous one, and is therefore not self-clocking
