ASCII Character Set

This appendix presents the material in the form of a table, provides ASCII character names and meanings, and clarifies what you enter from the keyboard.

Some commands described in this publication, such as the escape-character line configuration command in the "Terminal Line and Modem Support Commands" chapter require that you enter the decimal representation of an ASCII character.

Table A-1 provides code translations from ASCII characters to the decimal numbers. For example, the ASCII carriage return (CR) is decimal 13. This means that pressing Ctrl-M at your terminal generates decimal 13, which is interpreted as a CR.
