NAME

console − STREAMS-based console interface

DESCRIPTION

/dev/console and /dev/contty00 are synonyms for the system console and refer to an asynchronous serial data line originating from the system board. 

For security reasons, the permissions on /dev/console are set to 620, restricting writer access by group and other. This will cause applications writing to /dev/console to fail. If you have such an application, change the permissions on /dev/console as follows:

/bin/chmod 666 /dev/console

/dev/contty and /dev/contty01 refer to a second asynchronous serial data line originating from the system board.  /dev/contty02 and /dev/contty03 refer to a third and fourth serial data line originating from the system board.  These serial data lines are only available on the MVME187, MVME167, and MVME197 CPU boards. 

/dev/conctl is the console control port. 

These device special files access the STREAMS-based console driver which, when used in conjunction with the STREAMS line discipline module ldterm, supports the termios(2) and termio(7) processing.
