ANSI escape sequences are a standard for in-band signaling to control cursor location, color, font styling, and other options on video text terminals and terminal emulators. Certain sequences of bytes , most starting with an ASCII escape character and a bracket character, are embedded into text.
For example, the sequence of code 27 10, followed by the printable characters "[2;10H", would cause a Digital Equipment Corporation VT100 terminal to move its cursor to the 10th cell of the 2nd line of the screen. Several standards exist for these sequences, notably ANSI X3.64, but the number of non-standard variations is large.
ANSI.SYS is a device driver in the DOS family of operating systems that provides extra console functions through ANSI escape sequences.It is partially based upon a subset of the text terminal control standard proposed by the ANSI X3L2 Technical Committee on Codes and Character Sets (the "X3 Committee").
In 1973, ECMA-35 and ISO 2022 [18] attempted to define a method so an 8-bit "extended ASCII" code could be converted to a corresponding 7-bit code, and vice versa. [19] In a 7-bit environment, the Shift Out would change the meaning of the 96 bytes 0x20 through 0x7F [a] [21] (i.e. all but the C0 control codes), to be the characters that an 8-bit environment would print if it used the same code ...
This companion standard is needed to provide a resource that standardizes Configuration Management (CM) requirements specific to National Aeronautics and Space Administration (NASA) agreements and design activities. This Standard provides a template of CM requirements and user guidance for tailoring the requirements for each unique use case.
It also specifies a syntax for escape sequences, multiple-byte sequences beginning with the ESC control code, which can likewise be used for in-band instructions. [6] Specific sets of control codes and escape sequences designed to be used with ISO 2022 include ISO/IEC 6429, portions of which are implemented by ANSI.SYS and terminal emulators.
The IEEE 315 standard contains a list of Class Designation Letters to use for electrical and electronic assemblies. For example, the letter R is a reference prefix for the resistors of an assembly, C for capacitors, K for relays. Industrial electrical installations often use reference designators according to IEC 81346.
The systems, equipment, items, processes, modes, and sequences of operations to be tested by the CxP (contractors or others) should be detailed and identified in the design engineer's construction documents (drawings and specifications), the construction request for proposal (RFP), the contractors' bid submission, the commissioning ...
