(Add description of mainframe EOT usage.)
(fmt Unicode)
An EOT is often used to initiate other functions, such as releasing circuits, disconnecting terminals, or placing receive terminals in a [[standby]] condition.<ref name=1037c1996/> Its most common use today is to cause a [[Unix]] [[tty]] driver to signal [[end of file]] and thus exit programs that are awaiting input.
In [[ASCII]] and [[Unicode]], the character with the value 4 is EOT. It can be referred to as control-D, <tt>^D</tt> in [[caret notation]].{{Citation needed|date=March 2009}}. In Unicode, it is encoded at {{unichar|0004|'END OF TRANSMISSION|html=}}
