console(7) —
NAME
console − console interface
DESCRIPTION
The file /dev/console is a pseudo device driver for the system console, and can refer to a video adapter, a serial terminal, or no console (see the INTERACTIVE UNIX System Installation and Maintenance Guide). If the console refers to a video adapter, then this special file implements the features described in display(7).
Ioctl Calls
PIOCINFO defined in /usr/include/sys/cons.h: This request returns the system console’s type defined in /usr/include/sys/bootinfo.h header file. This request does not have any argument. Instead, the console’s type is returned to the ioctl() caller. Currently, the following consoles are supported:
| #define | CON_GAKD | 0 | /* Console refers to kd driver */ |
| #define | CON_NOCONS | 1 | /* No console */ |
| #define | CON_SERIAL | 2 | /* Console refers to asy driver */ |
PIOCDEV defined in /usr/include/sys/cons.h: This request returns the major and minor number of the console’s device node. This request does not have any argument. Instead, the console’s major and minor number is returned to the ioctl() caller. Any other requests will be passed to the proper physical driver.
