`ttymon` and the Console Port

Console services are not managed by the Service Access Controller nor any explicit ttymon administration file. An entry in the /etc/inittab file is used to manage the console port using ttymon in express mode, which is a special ttymon mode that is invoked directly by a command that requires login service.

The default console entry in the /etc/inittab file looks like this:

co:234:respawn:/usr/lib/saf/ttymon -g -h -p "`uname -n` console login: "
 -T terminal_type -d /dev/console -l console -m ldterm,ttcompat

`co:234:respawn:`	`co` identifies the entry as the console; `234` identifies the run levels for the action, `respawn`, which means the console entry should be restarted if it fails or doesn't exist at run levels 2, 3, and 4.
`/usr/lib/saf/ttymon -g -h`	The `-g` option is used so the correct baud rate and terminal setting can be set on a port and connect to a login service without being preconfigured by the SAC. The `-h` option forces a line hangup by setting the line speed to zero before setting the default or specified speed.
-p "`uname -n` console login:	Identifies the prompt string for the console port.
`-t` `terminal_type`	Identifies the terminal type of the console.
`-d /dev/console -l console -m ldterm,ttcompat`	The `-d` option identifies the console device; the `-l` option identifies the `ttylabel` in the `/etc/ttydefs` file; and the `-m` option identifies the STREAMS modules to be pushed.
