Flag Sequence

Flag sequence: In data transmission or processing, a sequence of bits used to delimit, i.e. mark the beginning and end of a frame.

Note 1: An 8-bit sequence is usually used as the flag sequence; for example, the 8-bit flag sequence 01111110.

Note 2: Flag sequences are used in bit-oriented protocols, such as Advanced Data Communication Control Procedures (ADCCP), Synchronous Data Link Control (SDLC), and High-Level Data Link Control (HDLC).

Famous quotes containing the word flag:

    —Here, the flag snaps in the glare and silence
    Of the unbroken ice. I stand here,
    The dogs bark, my beard is black, and I stare
    At the North Pole. . .
    And now what? Why, go back.

    Turn as I please, my step is to the south.
    Randall Jarrell (1914–1965)
