Some commands described in this publication, such as the terminal escape-character EXEC command, require 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 character 13. Pressing Ctrl-M at your terminal generates decimal character 13, which is interpreted as a CR.
