.TH GETTYDEFS 4 .SH NAME gettydefs \- speed and terminal settings used by getty .SH DESCRIPTION The .B /etc/gettydefs file contains information used by .IR getty (1M) (see the .IR "U\s-1NIX\s+1 System Administrator's Manual" ) to set up the speed and terminal settings for a line. It supplies information on what the .I login prompt should look like. It also supplies the speed to try next if the user indicates the current speed is not correct by typing a .I <break> character. .PP Each entry in .B /etc/gettydefs has the following format: .PP .RS label# initial-flags # final-flags # login-prompt #next-label .RE .PP Each entry is followed by a blank line. Lines that begin with .B # are ignored and may be used to comment the file. The various fields can contain quoted characters of the form .BR \eb , .BR \en , .BR \ec , etc., as well as .BI \e nnn\fR,\fP where .I nnn is the octal value of the desired character. The various fields are: .TP \w'login-prompt\ \ \ 'u .I label This is the string against which .I getty tries to match its second argument. It is often the speed, such as \fB1200\fP, at which the terminal is supposed to run, but it needn't be (see below). .TP .I initial-flags These flags are the initial .IR ioctl (2) settings to which the terminal is to be set if a terminal type is not specified to .IR getty . .I Getty understands the symbolic names specified in .B /usr/include/sys/termio.h (see .IR termio (7) in the \fIU\s-1NIX\s+1 System Administrator's Manual\fP). Normally only the speed flag is required in the .IR initial-flags . .I Getty automatically sets the terminal to raw input mode and takes care of most of the other flags. The \fIinitial-flag\fP settings remain in effect until .I getty executes .IR login (1). .TP .I final-flags These flags take the same values as the .I initial-flags and are set just prior to .I getty executes .IR login . The speed flag is again required. The composite flag .SM .B SANE takes care of most of the other flags that need to be set so that the processor and terminal are communicating in a rational fashion. The other two commonly specified .I final-flags are .SM .BR TAB3\*S , so that tabs are sent to the terminal as spaces, and .SM .BR HUPCL\*S , so that the line is hung up on the final close. .TP .I login-prompt This entire field is printed as the \fIlogin-prompt\fP. Unlike the above fields where white space is ignored (a space, tab or new-line), they are included in the .I login-prompt field. .TP .I next-label This indicates the next .I label of the entry in the table that .I getty should use if the user types a .I <break> or the input cannot be read. Usually, a series of speeds are linked together in this fashion, into a closed set. For instance, \fB2400\fP linked to \fB1200\fP, which in turn is linked to \fB300\fP, which finally is linked to \fB2400\fP. .PP If .I getty is called without a second argument, then the first entry of .B /etc/gettydefs is used, thus making the first entry of .B /etc/gettydefs the default entry. It is also used if .I getty can't find the specified .IR label . If .B /etc/gettydefs itself is missing, there is one entry built into the command which will bring up a terminal at \fB300\fP baud. .PP It is strongly recommended that after making or modifying .BR /etc/gettydefs , it be run through .I getty with the check option to be sure there are no errors. .SH FILES /etc/gettydefs .SH "SEE ALSO" getty(1M), termio(7) in the \fIU\s-1NIX\s+1 System Administrator's Manual\fP. .br login(1), ioctl(2). .\" @(#)gettydefs.4 5.2 of 5/18/82
