Also, news transmissions from agencies to newspapers or TV stations used (maybe still use in some places) a format called IPTC 7901 which also makes use of the SOH, SOT, EOT and EOH codes: https://www.iptc.org/std/IPTC7901/1.0/specification/7901V5.pdf https://www.iptc.org/std/IPTC7901/1.0/specification/7901V5.p... This stems from them coming via a serial wire (which is why news updates are also called “wires” in that context) to a TTY. (Nowadays, you’d have a server receiving everything over the Internet and spitting it out in this format via a serial port or Telnet connection if needed.) According to Wikipedia, fancier news messages are possible using some more codes, but I’ve never seen them in the wild in recent years: https://en.wikipedia.org/wiki/IPTC_7901#C0_control_codes https://en.wikipedia.org/wiki/IPTC_7901#C0_control_codes
