- Most serial devices are named “tty” in Unix and Unix-like systems.
- Modern terminals/CLIs are literally emulations of a teletype interface.
- The BEL or ALERT character, which in most computers today plays the system’s alert sound, originated in teletypes as a literal ringing of a bell.
- ASCII, perhaps the best-known characterset of the modern day though it has evolved to more extensive charactersets, is the direct predecessor of descendant of ITA2/USTTY, the charactersets most extensively used to one degree or another by the most prolific and iconic teletype equipment; these were still used in some teletype equipment even after ASCII was standardized and popularized in the latter half of the 20th century
- LF (line feed, or newline) and CR (carriage return)—invisible characters that control the cursor to advance to the next line on the screen—were used in teletypes to do the same thing on physical paper.
- The the term “baud” derives from the name “Emille Baudot”, who invented the first iteration of encoding teletypes came to use. Baud is the rate of speed that teletypes can transmit. Older teletypes transmit at a speed of 45.45 baud; at 45 baud, an average JPEG would take 7-8 days to download.
