TTY/Teleprinter or Telecommunications device for the deaf
(note: TTY uses Baudot code, not ASCII. This uses 5 bits per character instead of 8, and one start and 1.5 stop bits.)

TTY (V.18) 45 bit/s  6 cps TTY (V.18) 50 bit/s  6.71 cps



Modems
(note: serial, 1 start bit, 8 data bits, 1 stop bit: therefore 10 bits needed to transmit each byte. The exception is 110 baud which uses 2 stop bits or 11 bits per byte.)
