GETTY(8)						      System Manager's Manual							  GETTY(8)

NAME
getty - set typewriter mode SYNOPSIS
/etc/getty [ char ] DESCRIPTION
Getty is invoked by init(8) immediately after a typewriter is opened following a dial-up. It reads the user's login name and calls login(1) with the name as argument. While reading the name getty attempts to adapt the system to the speed and type of terminal being used. Init calls getty with a single character argument taken from the ttys(5) file entry for the terminal line. This argument determines a sequence of line speeds through which getty cycles, and also the `login:' greeting message, which can contain character sequences to put various kinds of terminals in useful states. The user's name is terminated by a new-line or carriage-return character. In the second case CRMOD mode is set (see ioctl(2)). The name is scanned to see if it contains any lower-case alphabetic characters; if not, and if the name is nonempty, the system is told to map any future upper-case characters into the corresponding lower-case characters. If the terminal's `break' key is depressed, getty cycles to the next speed appropriate to the type of line and prints the greeting message again. Finally, login is called with the user's name as argument. The following arguments from the ttys file are understood. 0 Cycles through 300-1200-150-110 baud. Useful as a default for dialup lines accessed by a variety of terminals. - Intended for an on-line Teletype model 33, for example an operator's console. 1 Optimized for a 150-baud Teletype model 37. 2 Intended for an on-line 9600-baud terminal, for example the Textronix 4104. 3 Starts at 1200 baud, cycles to 300 and back. Useful with 212 datasets where most terminals run at 1200 speed. 5 Same as `3' but starts at 300. 4 Useful for on-line console DECwriter (LA36). SEE ALSO

NAME
getty - set terminal type, modes, speed, and line discipline SYNOPSIS
/usr/lib/saf/ttymon [-h] [-t timeout] line [ speed [ type [linedisc]]] /usr/lib/saf/ttymon -c file DESCRIPTION
getty sets terminal type, modes, speed, and line discipline. getty is a symbolic link to /usr/lib/saf/ttymon. It is included for compati- bility with previous releases for the few applications that still call getty directly. getty can only be executed by the super-user, (a process with the user ID root). Initially getty prints the login prompt, waits for the user's login name, and then invokes the login command. getty attempts to adapt the system to the terminal speed by using the options and arguments specified on the command line. Without optional arguments, getty specifies the following: The speed of the interface is set to 300 baud, either parity is allowed, NEW- LINE characters are converted to carriage return-line feed, and tab expansion is performed on the standard output. getty types the login prompt before reading the user's name a character at a time. If a null character (or framing error) is received, it is assumed to be the result of the user pressing the BREAK key. This will cause getty to attempt the next speed in the series. The series that getty tries is determined by what it finds in /etc/ttydefs . OPTIONS
The following options are supported: -h If the -h flag is not set, a hangup will be forced by setting the speed to zero before setting the speed to the default or a specified speed. -t timeout Specifies that getty should exit if the open on the line succeeds and no one types anything in timeout seconds. -c file The -c option is no longer supported. Instead use /usr/sbin/sttydefs -l to list the contents of the /etc/ttydefs file and perform a validity check on the file. OPERANDS
The following operands are supported: line The name of a TTY line in /dev to which getty is to attach itself. getty uses this string as the name of a file in the /dev directory to open for reading and writing. speed The speed argument is a label to a speed and TTY definition in the file /etc/ttydefs. This definition tells getty at what speed to run initially, what the initial TTY settings are, and what speed to try next, (should the user press the BREAK key to indicate that the speed is inappropriate). The default speed is 300 baud. type and linedisc These options are obsolete and will be ignored. FILES
