ASCII Character Set

ASCII Character Set

Some commands described in this manual require that you enter the decimal representation of an ASCII character. Table D-1 provides code translations from ASCII characters to 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.
