ASCII Character Set and Hex Values
Some commands described in the Cisco IOS documentation set, such as the escape-character line
configuration command, require that you enter the decimal representation of an ASCII character. Other
commands, such as the snmp-server group command, make use of hexadecimal representations.
Table 136 provides code translations from the decimal numbers to their hexadecimal and ASCII
equivalents. It also provides the keyword entry for each ASCII character. For example, the ASCII
carriage return (CR) is decimal 13. Entering Ctrl-M at your terminal generates decimal 13, which is
interpreted as a CR.
