cuegetty(1M)

NAME

cuegetty — set terminal type, modes, speed, and line discipline for CUE

SYNOPSIS

/usr/sbin/cuegetty [-L nls_language] [-T terminal_type] [-h] [-t timeout] line [speed]

DESCRIPTION

The cuegetty command, which is very similar to getty(1M), is the second process in the series, (init-cuegetty-cue-work session) that ultimately connects a user with the HP-UX CUE system. It is invoked by init to monitor the terminal lines configured on a system (see init(1M)). Each cuegetty process resets its process group using setpgrp, opens a particular terminal line, and usually sleeps in the open() until the machine senses a hardware connection for the terminal. When open() returns, cuegetty attempts to adapt the system to the terminal speed and type, and displays the contents of the /etc/issue file, if it exists. Lastly, cuegetty invokes cue which displays the Login screen and performs user validation (see cue(1)).

To start cuegetty, an entry for cuegetty should be placed in the /etc/inittab file. A typical CUE entry in the /etc/inittab file resembles the following:

cue:2:respawn:/usr/sbin/cuegetty -L fr_FR.roman8 -h tty0p1

See /usr/newconfig/etc/cue.inittab for an example /etc/inittab file. See cue(1) for more details on the CUE system.

Configuration Options and Arguments

cuegetty recognizes the following arguments:

line

Name of a tty line in /dev to which cuegetty is to attach itself. cuegetty uses this string as the name of a file in the /dev directory to open for reading and writing. By default cuegetty forces a hangup on the line by setting the speed to zero before setting the speed to the default or specified speed. However, when cuegetty is run on a direct port, cuegetty does not force a hangup on the line since the driver ignores changes to zero speed on ports open in direct mode (see modem(7)).

-L

nls_language is used to set the language for the CUE login screens. If the message catalog, cue.cat, does not exist for nls_language, the default native language, C, is used.

-T

terminal_type is used to specify the type of terminal that cuegetty will be initiated on. Allowed values are vt320, vt100, wy60, and hp. The default is hp.

-h

Tells cuegetty not to force a hangup on the line before setting the speed to the default or specified speed.

-t timeout

cuegetty exits if the open on the line succeeds and nothing is typed within timeout seconds.

speed

A label to a speed and tty definition in the file /etc/gettydefs. This definition tells cuegetty at what speed to initially run, what the login message should look like, what the initial tty settings are, and what speed to try next should the user indicate that the speed is inappropriate (by typing a break character). The default speed is 300 baud.

When no optional arguments appear on the command line, cuegetty sets the terminal interface as follows:

Interface speed: 300 baud
Raw mode (awaken on every character)
Echo suppressed
Parity: either
New-line characters: convert to carriage-return, line-feed pair
Expand tabs on the standard output
Type login message then read user's name, one character at a time
If a null character (or framing error) is received, assumed it to be the result of the user pushing the "break" key. This causes cuegetty to attempt the next speed in the series. The series that cuegetty tries is determined by what it finds in /etc/gettydefs.

After interface set-up is complete, cue is started to accept and validate the user name and password.

WARNINGS

If a supported non-HP terminal (or an HP terminal such as HP 700/60 in VT320, VT100 or WYSE60 mode) is required to run cuegetty, make sure that a correct terminal type is specified using the -T option. For example, if you want to run cuegetty on a vt100 terminal, you should make an entry in the /etc/inittab file such as the following entry:

tty1:23:respawn:cuegetty -T vt100 -h tty1p1 9600

Absence of the -T option causes cuegetty to assume terminal to be a HP terminal which may then cause the terminal to behave incorrectly and may not even allow user to login.

DEPENDENCIES

cuegetty is available only on Series 800 systems, and is compatible only with the following terminals:

HP700/92   HP700/94   HP2392   HP2394   VT100   WYSE60

See WARNINGS if you intend to use a non-HP terminal (or an HP terminal such as HP 700/60 in VT320, VT100, or WYSE60 mode).

FILES

/etc/gettydefs: contains speed and terminal settings used by cuegetty
/etc/inittab: init reads this file to determine which processes to spawn
/etc/issue: contains issue identification data
/usr/newconfig/etc/cue.inittab: sample inittab file with cuegetty entry
