This part of ISO/IEC 9834 specifies the contents of register entries recording information about VT control object Definitions and assigning unambiguous names of ASN.1 type OBJECT IDENTIFIER to VT CO Definitions. The VT COs specified in this register are defined for use with implementations of VT protocols claiming to conform to ISO 9041-1. The VTE CO names to which this document refers are for use in fields of the VT communication protocol defined in ISO 9041-1 which need to identify the VT CO definitions defined in the register entries. A name registered in accordance with this part of ISO/IEC 9834 shall serve as an identification of the VT CO definition associated with it in the register. The presence of a register entry in the International Register carries no implications of required support for that VT CO definition in any Virtual Terminal implementation. NOTE — Nonetheless, within a VT CO definition entry, requirements may be expressed relating to implementations claiming to support the entry. The requirement for registration for the following CO classification has been identified in ISO 9040: — Field Entry Instruction COs (FEICOs) — Field Entry Pilot COs (FEPCOs) — Reference Information Objects (RIOs) — Termination Conditions COs (TCCOs) In addition there is a requirement for the registration of miscellaneous COs. Future VT standards may identify registration requirements for new CO classifications.
