Normal I/O control parameters for individual lines are managed by ioctl(2) calls. Line speeds may be initiated via the ttys(5) file, stty(1) or ifconfig(8) to name a few, see tty(4).
The dz
driver monitors the rate of input
on each board, and switches between the use of character-at-a-time
interrupts and input silos. While the silo is enabled during periods of
high-speed input, the driver polls for input 30 times per second.
dz
driver appeared in NetBSD
6.0.
