    Abstract - (Show below) - (Hide below)

    Covers asynchronous data transmission with half duplex and duplex link protocols operating with window size one for message transfers. Specifies standards on coding, formatting and synchronizing data frames of variable and fixed lengths which meet specified data integrity requirements.

    Scope - (Show below) - (Hide below)

    This series of standards applies to telecontrol equipment and systems with coded bit serial data transmission for monitoring and controlling geographically widespread processes. This standard covers asynchronous data transmission with half duplex and duplex link protocols operating with window size one for message transfers.
