From the 1980s, teleprinters were replaced by computers running teleprinter emulation software. Creed & Company, a British company, built teleprinters for the GPO's teleprinter service. The teleprinter, or Teletype, got financial quotes and printed them out on a ticker tape. TTY stands for "TeleTYpe" or "TeleTYpewriter", and is also known as Teleprinter or Teletype. Messages were sent to and fro across the Atlantic by enciphered teleprinter links. The German military also deployed several teleprinter stream ciphers. This was passed to the analysis and evaluation section by Teleprinter or Wireless telegraphy. This led the British to use the code Fish for the German teleprinter cipher system. In late 1942, he transferred to work on German teleprinter ciphers. Communication with Bletchley Park was by teleprinter links. The X3.2 subcommittee designed ASCII based on the earlier teleprinter encoding systems. Radioteletype evolved from these earlier landline teleprinter operations. Radioteletype evolved from earlier landline teleprinter operations that began in the mid-1800s. The SZ machine served as an in-line attachment to a standard Lorenz teleprinter. The Germans also developed a series of teleprinter encryption systems, quite different from Enigma.
