C0C1kontrollkoder

C0C1kontrollkoder refers to a specific sequence of control characters, namely C0 (character code 0) and C1 (character code 1), often used in telecommunications and data transmission for signaling or control purposes. These codes are part of the broader ASCII (American Standard Code for Information Interchange) or extended ASCII character sets.

Control characters are non-printable characters that perform various functions in data processing and communication. C0, typically represented by the null character (NUL), is often used as a filler, a padding character, or to indicate the end of data. C1, sometimes referred to as SOH (Start of Heading) in some contexts, can signal the beginning of a message or a specific section of data. The exact interpretation and usage of C0 and C1 can vary depending on the specific protocol or system employing them.

In some older communication systems, these control characters were crucial for establishing connections, synchronizing data streams, and managing the flow of information between devices. Their precise byte values and the meanings assigned to them were defined by the standards governing the particular communication channel. While modern systems often use more complex protocols, understanding the role of basic control characters like C0 and C1 provides insight into the foundational principles of data transmission. The term "C0C1kontrollkoder" emphasizes their sequential use as a pair for a specific control function.
