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 is encoded at {{unichar|0004|END OF TRANSMISSION}}. It can be referred to as control-D, <tt>^D</tt> in [[caret notation]]. Unicode provides the character {{unichar|2404|SYMBOL FOR END OF TRANSMISSION|html=}} for when EOT needs to be displayed graphically.
