zstty driver provides TTY support for Zilog 8530
  Dual UART chips.
Input and output for each line may set to any baud rate in the range 50 to 38400 (and higher on some machines).
The PPS_SYNC option enables code to use the Data Carrier Detect (DCD) signal line for attachment to an external precision clock source (e.g., GPS, CDMA) which generates a Pulse Per Second (PPS) signal. This is used by ntpd(8) to discipline the system clock, and more accurately count/measure time. See options(4) for more discussion.
zstty driver was derived from the
  sparc zs driver supplied with
  4.4BSD UNIX.
