Handshaking
  • In data communication, a sequence of events governed by hardware or software, requiring mutual agreement of the state of the operational modes prior to change.
  • The process used to establish communications parameters between two stations.
  • Note: Handshaking follows the establishment of a circuit between the stations and precedes information transfer. It is used to agree upon such parameters as information transfer rate, alphabet, parity, interrupt procedure, and other protocol features. See also protocol.
