+.TH GETTY.VM 8 
+.UC
+.SH NAME
+getty.vm  \- set terminal mode
+.SH SYNOPSIS
+.B /etc/getty.vm
+[ char ]
+.SH DESCRIPTION
+.I Getty.vm
+is invoked by
+.IR  init.vm (8)
+immediately after a terminal is opened,
+following the making of a connection.
+While reading the name
+.I getty.vm
+attempts to adapt the system to the speed and type of terminal
+being used.
+.PP
+.I Init.vm
+calls
+.I getty.vm
+with an argument specified by the
+.I ttys
+file entry for the terminal line.
+Arguments other than `0' can be used to make
+.I getty.vm
+treat the line specially.
+Normally, it
+sets the speed of the interface to 300 baud,
+specifies that raw mode is to be used (break on every character),
+that echo is to be suppressed, and either parity
+allowed.
+It types a banner identifying the system (from
+<ident.h> and the `login:' message.
+Then the user's name is read, a character at a time.
+If a null character is received, it is assumed to be the result
+of the user pushing the `break' (`interrupt') key.
+The speed is then
+changed to 1200 baud and the `login:' is typed again;
+a second `break' changes the speed to 150 baud and the `login:'
+is typed again.  Successive `break' characters cycle through the
+speeds 300, 1200, and 150 baud.
+.PP
+The user's name is terminated by a new-line or
+carriage-return character.
+The latter results in the system being set to
+treat carriage returns appropriately (see
+.IR  stty (2)).
+.PP
+The user's 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.
+.PP
+Finally, login is called with the user's name as argument.
