An EOT is often used to initiate other functions, such as releasing circuits, disconnecting terminals, or placing receive terminals in a [[standby (electricity)|standby]] condition.<ref name=1037c1996/> Its most common use today is to cause a Unix [[computer terminal|terminal]] 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 {{keypress|Ctrl|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.<ref>{{cite web| title = Control Pictures| url = httphttps://www.unicode.org/charts/PDF/U2400.pdf| accessdate = 2013-04-06}}</ref> In addition, {{unichar|2301|ELECTRIC ARROW}} can also be used as a graphic representation of EOT; it is defined in Unicode as "symbol for End of Transmission".<ref>{{cite web
