Introduction
This amendment to ISO/IEC 7809:1993 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.
This amendment adds details necessary in extending the modulus beyond 128 and also the introduction of the information field in the mode-setting commands/responses.
