NameSynchronous idle
Unicode numberU+0016
CategoryASCII Table1. ASCII control characters
DescriptionThe Unicode character U+0016, also known as "Synchronous Idle", belongs to the "C0 Controls and Basic Latin" block and falls under the "Control" category in the Unicode standard. The Synchronous Idle control code is a legacy from telecommunication protocols, originally used in systems that utilize synchronous transmission. These systems use a constant stream of bits and need special control codes to help maintain synchronization when no data is being transmitted. This character has no graphical representation, as it is a control character. Its specific function can vary depending on the system and context in which it is used.
