       getty  - set terminal type, modes, speed, and line discipline

       timeout] line [speed [type [linedesc]]]


       The  program is invoked by (see init(1M)), as the second process in the
       series, > > > shell, that ultimately connects a	user  with  the	 HP-UX

       sets  the terminal speed and characteristics and prompts for the user's
       login information before passing control to the program.	 See below for

       recognizes the following options:

	      Scan and test  file  for	conformance with the specifications in
			     the gettydefs(4) manpage, print  the  results  on
			     standard  output, and terminate.  All other argu‐
			     ments are ignored.

			     Any unrecognized modes or improperly  constructed
			     entries  are  reported  as	 errors.   For correct
			     entries, prints out the  values  of  the  various
			     flags.   See  ioctl(2)  for  an interpretation of
			     values.  Note that some values are added  to  the
			     flags automatically.

	      Get the settings for special control characters from the
			     file.  See the section.

	      Do not force a hangup on the line before setting the speed.

			     By	 default,  forces a hangup on the line by set‐
			     ting the speed to zero before setting  the	 speed
			     to the default or specified speed.	 However, when
			     is run on a direct port, does not force a	hangup
			     on	 the  line since the driver ignores changes to
			     zero speed on ports  open	in  direct  mode  (see

	      Exit if the open on the line succeeds
			     and no one types anything within timeout seconds.
			     The default is to wait indefinitely.

       recognizes the following operands:

	      line	     The name of a tty device file in to which	is  to
			     attach  itself.  opens file for reading and writ‐

	      speed	     A label for a speed and  tty  definition  in  the
			     file See gettydefs(4).

			     This  definition  tells at what speed to run ini‐
			     tially, what the login message should look	 like,
			     what the initial tty settings are, and what speed
			     to try next if the user indicates that the	 speed
			     is	 inappropriate	by  typing  a break character.
			     The default speed is the first entry  in  or  300
			     baud if is missing or unusable.

	      type	     A character string describing what type of termi‐
			     nal is connected to the line in question.	under‐
			     stands the following types:

			     none    Default
			     c100    Concept 100
			     hp45    Hewlett-Packard HP2645
			     vt61    DEC vt61
			     vt100   DEC vt100

			     The  default terminal is that is, any CRT or nor‐
			     mal terminal unknown to the  system.   Also,  for
			     terminal  type  to	 have any meaning, the virtual
			     terminal handlers must be compiled into the oper‐
			     ating  system.   They are available, but not com‐
			     piled, in the default condition.

	      linedesc	     A character string describing which  line	disci‐
			     pline  to	use when communicating with the termi‐
			     nal.  Hooks for line disciplines are available in
			     the  operating  system,  but  there  is  only one
			     presently available: the default line discipline,

       With the option, tests file against the rules for  (see	gettydefs(4)),
       prints  error  messages	and flag values to standard output, and termi‐

       This is a good way to test a revised file before putting it into opera‐

       Without	the option, opens the port interface for line, sets the speed,
       terminal parameters, and login message, prompts for login  information,
       and passes control to the program, as follows.

       1.     determines the speed, terminal parameters, and login message.

	      ·	 If  the  speed	 operand is given, selects that entry from and
		 sets the terminal parameters and login message to  the	 given

	      ·	 If  speed  is	not  found in or the speed operand is omitted,
		 selects the first entry from and sets the terminal parameters
		 and login message to the given values.

	      ·	 If  is missing or unreadable or has errors, sets the speed of
		 the interface to 300 baud, sets the login message to and sets
		 the  terminal	parameters  to:	 use raw mode (awaken on every
		 character), suppress echo, allow either parity, convert  new‐
		 line  characters to carriage-return-linefeed, and perform tab
		 expansion on standard output,

	      ·	 If type or linedesc is given,	the  terminal  parameters  are
		 adjusted appropriately.

	      ·	 The special control characters are defined.  If the option is
		 given, they are read from the	file.	See  the  section  for

	      ·	 connects  to  the  terminal  port,  applying all the terminal
		 parameters.  It forces a hangup on the line  by  setting  the
		 speed to zero, except if the port is opened in direct mode or
		 if the option was specified.

       2.     prompts for and reads a line of login information.

	      ·	 If the file exists, it is displayed.

	      ·	 The login message is displayed.

	      ·	 reads the user name and optional  arguments  from  the	 port.
		 The one-line parsed input is limited to 255 characters and 64
		 whitespace-delimited words.  The special  control  characters
		 affect the input.  See the section for detail.

		 If  a	null  character	 or a framing error is received, it is
		 assumed to be the result of the user pushing the  break  key.
		 This  causes to attempt the next speed in the current series,
		 repeating step 1.

		 The input line is  terminated	with  a	 newline  or  carriage
		 return	 character.   If  the  latter,	the  system  is set to
		 receive carriage returns appropriately (see termio(7)).

		 The user's name is scanned to see if it contains  any	lower‐
		 case  alphabetic characters.  If it does not, and if the name
		 is nonempty, the system is told to map any  future  uppercase
		 characters into the corresponding lowercase characters.

       3.     passes control to

	      ·	 passes	 the  parsed  user  name and optional arguments, along
		 with the terminal parameters, to the program (see exec(2)).

	      ·	 performs user validation (for example,	 password  processing)
		 and  login retries, places the optional arguments in environ‐
		 ment  variables,  and	passes	control	 to  the  shell.   See
		 login(1) for details.

       4.     On termination, control returns to

	      ·	 When  or  or  the  shell  terminate  for  any reason, control
		 reverts to

	      ·	 If the action is defined for the device file  in  reruns  the
		 command, and the process resumes at step 1 (see inittab(4)).

   Special Control Characters
       The program uses special control characters to manage text input and to
       switch line speeds.

       The default special control characters are shown in the	following  ta‐

       Table 1:	 Default Special Control Characters

		 May Be	  Character, or ASCII Value
       Name	 Quoted	      (ASCII Name; Key Names)	Action
       eof	  Yes	  ^D  (EOT)			Terminate getty
       erase	  Yes	  #				Erase previous character
       intr	   No	  127 (DEL; Delete)		Erase entire input line
       kill	  Yes	  @				Erase entire input line
       quit	   No	  ^\  (FS)			Terminate getty

       break	   No	  \0  (NUL or framing error)	Switch to next entry
       lineend	   No	  ^J  (NL; newline)		Terminate input line
       lineend	   No	  ^M  (CR; carriage return)	Terminate input line
       quote	  Yes	  \				Quote next character
       You  can set different values for and some other terminal parameters by
       modifying the file.  A superuser may view and modify with the  command.

       stands the single character  quoting  convention	 using	the  backslash
       quote.  This allows you to include whitespace, some of the special con‐
       trol characters, and some of the general	 control  characters,  in  the
       input  line  as	ordinary text.	You cannot quote the current values of
       the special control character names that are marked "No" in the May  Be
       Quoted  column.	 The  single  and double quotation marks and ) have no
       special meaning (unless they are assigned in

       The modem control parameter must be present in the file when  using  in
       conjunction  with  an  HP2334 or HP2335 MultiMux to ensure that the RTS
       modem control signal is asserted correctly.
