EDIT End Of Text (Ctrl-C) Marks the end of the message portion of a data stream.
 
EDIT Modern Usage In many operating systems and command line interfaces, Ctrl-C is interpreted as a break or interrupt signal.

In Unix and CP/M, pressing Ctrl-C generally causes the current running program to terminate. This is also the case with many Basic interpreters. MS-DOS programs do not respond to Ctrl-C, but rather the Ctrl-Break key combination.

In command line interfaces, Ctrl-C causes whatever has been typed so far at the current prompt to be ignored and issues a new prompt.

In Graphical User Interfaces, Ctrl-C is generally a shortcut for the copy editing action.
 
EDIT Suggested Implementation When an ETX is received the current process should be terminated normally, if applicable, or aborted.
