dz
— eMIPS console
serial device interface
dz* at ebus0 addr ?
This serial line provides a simple communication line with no modem control. It is not adequate for UNIX dialup use.
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.
A dz
driver appeared in
NetBSD 6.0.
