DESCRIPTION

       iserial	determines  if the underlying character device of the current stdin is a serial line.  This can be used on /dev/console as current
       character device to check if the console is a serial line.

       The exit status of iserial is 0 if stdin is a serial line otherwise not.

FILES

       /dev/console
	      the system console.

NAME

       Showconsole - determines the underlying tty of stdin
       Setconsole - sets the underlying tty of /dev/console

SYNOPSIS

       showconsole [-n]

       setconsole /dev/tty<xy> < /dev/console

DESCRIPTION

       showconsole  determines the underlying character device of the current stdin.  This can be used on /dev/console as current character device
       to get the real character device back.

       setconsole sets the underlying tty of the system console /dev/console.  This requires that the standard input is identical  with  /dev/con-
       sole and exactly one argument, a valid character device is given.

OPTIONS

       -n     Return  the  major and minor device numbers instead of the device file name.  This can be used to asked the kernel for the major and
	      minor device numbers of a not existing device file in /dev.

BUGS

       showconsole needs a mounted /proc file system and tries to set the controlling tty to stdin if no controlling tty is found.  After  reading
       /proc the status of the controlling tty is restored to avoid problems with getty processes.

FILES

       /proc/<pid of showconsole>/stat
	      the stat file of the showconsole process.

       /dev/console
	      the system console.
