Communication Control Characters
Listed below in alphabetical order are the expanded text
meanings for common ANSI communication control characters, and two-character
system abbreviation for each one. Some abbreviations have forward slash
characters between the two letters. This is to differentiate the abbreviations
for a control character from a hex number. For example, the abbreviation
for Form Feed is listed as F/F, to differentiate it from the hex number
FF.
