ISO/IEC 7809 Replaced
ISO/IEC 7809:1993/AMD10:1995
Information technology - Telecommunications and information exchange between systems - High-level data link control (HDLC) procedures - Classes of procedures - Amendment 10: Extension of HDLC sequence number modulus beyond 128
Increases the modulus number (i.e. the sequence number) in steps up to a maximum of 2 147 483 648 which can be represented in 31 bits. This is done by the introduction of a new "Set Mode" command that can be used to negotiate or indicate the modulus in absence of, or to override, a default value. This uses an optional information field in the "Set Mode" command.
