TTYTAB

NAME
ttytab - table of login terminals

SYNOPSIS
/etc/ttytab

DESCRIPTION
The ttytab file lists all the terminal devices that one can login on. It is a simple text file that contains lines of the form:

    name    type    "getty"    "init"

The name and type fields are simple words, name is the name of the terminal device with /dev stripped off, and type tells the type of terminal to initialize the TERM environment variable.

The getty and init fields may name commands that are run to allow one to login on the line, or to initialize the line. Both these fields may be more than one word if the whole field is enclosed in double quotes. Getty is usually simply the word getty, the command that prints a system identification banner and allows on to type a name to log in. Init is usually an stty command to set the baud rate and parity of a serial line.

The init field may be omitted to indicate that no initialization is necessary, and the getty field may be left out to not start a login process. Terminals should not be left out, because their place in the ttytab file determines their slot number as returned by ttyslot(3).

Comments (introduced by #) and empty lines are ignored.

EXAMPLE
A ttytab for the console, two serial lines, and a pseudo tty entry:

    console	minix	getty
    tty00	vt100	getty	"stty 9600"
    tty01	dialup	getty	"stty 38400"
    ttyp0	network

ENVIRONMENT

TERM
    Terminal type

NOTES
It is customary to set the type to dialup for a dialin line. One can check for that name in one's .profile.

SEE ALSO
getttyent(3), ttyslot(3), init(8).
