Information technology - Data interchange on 130 mm optical disk cartridges - Capacity: 1,3 gigabyte...
This International Standard specifies
- the conditions for conformance testing;
- the environments in which the cartridges are to be operated and stored;
- the mechanical, physical and dimensional characteristics of the case and of the cartridges, so as to provide mechanical interchangeability between the data processing systems;
- the format of the information on the disk, both embossed and user…

Defines a single-exchange negotiation procedure for establishing operational characteristics when either one or more HDLC stations are capable of providing multiple selections. Provides a means for interchanging the necessary information to establish, at a minimum, a data link connection between two correspondents wishing to communicate. Describes the general purpose XID frame information field…

Specifies the frame structure for data communication systems using bit-oriented high-level data link control (HDLC) procedures. Defines the relative positions of the various components of the basic frame and the bit combination for the frame delimiting sequence (flag). The mechanisms used to achieve bit pattern independence (transparency) within the frame are also defined. In addition, two frame…

Describes the HDLC unbalanced classes of procedures, the HDLC balanced class of procedures, and the HDLC connectionless classes of procedures for synchronous or start/stop data transmission. The procedures use the HDLC frame structure defined in ISO/IEC 3309 and the HDLC elements of procedures described in ISO/IEC 4335.

Specifies elements of data link control procedures for synchronous or start/stop, code-transparent data transmission using the HDLC frame structure specified in ISO/IEC 3309 and independent frame numbering in both directions. These HDLC elements of procedures are defined specifically in terms of the actions that occur on receipt of commands at a secondary station or a combined station.
Information technology - Portable Operating System Interface (POSIX) - Part 2: Shell and Utilities
This part of ISO/IEC 9945 defines a standard source-code-level interface to command interpretation, or "shell," services and common utility programs for applica- tion programs. These services and programs are complementary to those specified by ISO/IEC 9945-1: 1990 (IEEE Std 1003.1-1990) {8}, hereinafter referred to as "POSIX.1 {8}." When the User Portability Utilities Option…
