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/s6 cps TTY (V.18)50 bit/s6.71 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.)
