Noun used with modifier

  • input: If the input baud rate is set to zero, the input baud rate is specified by the value of the output baud rate.
  • output: The input and output baud rates are stored in the termios structure.
  • 56k: The uplink is at dial-up speeds, 56k baud so sending large attachments could be a problem.
