INITIA Command

Function

     The INITIA command sets the parameters for your  terminal.   This
     command  is  issued  automatically  at  system startup on certain
     designated terminals.  You can reissue the command at  any  time.
     This  command  also  starts  certain system programs, when issued
     from particular terminals.

     If you are logged in  and  you  run  INITIA,  INITIA  reads  your
     SWITCH.INI  file.  For more information about SWITCH.INI, see the
     help file SWINI.

Format

     INITIA arg arg ...

     Where:  arg can be one  of  the  following  arguments.   You  can
             precede  any  of  the following arguments with NO (except
             NORUN) to suppress a default setting.

          Argument                         Function

          ATTRIBUTES     Prints  the  terminal  attributes  for   this
                         terminal.

          CHECK:keyword  Sets  your  terminal  type  after  requesting
                         identification  from  your DEC terminal.  The
                         optional keyword is  DEFAULT,  meaning  CHECK
                         only  if  the  current  terminal  type is the
                         default type (usually TTY).

          HELP           Prints information about INITIA command.

          KSYS           Tells you when timesharing will end (if  KSYS
                         is set).

          NAME           Prints the  system  name  on  your  terminal.
                         NAME is the default argument.

          NORUN          Suppresses  the  execution  of  any   default
                         program.

          NOTICE         Prints the general operator notice.

          SETTTY         Sets  up  your  terminal  characteristics  or
                         attributes.   The SETTTY argument is required
                         in order to set terminal characteristics from
                         SWITCH.INI  if  you  are logged in.  When you
                         are not  logged  in,  INITIA  reads  terminal
                         characteristics        from       SYS:TTY.INI
                         automatically.  SETTTY can  be  specified  on
                         the  INITIA command line or in the SWITCH.INI
                         file.

          STRUCTURES     Prints any  operator  notices  about  mounted
                         structures.

          TEXT           Prints quick operator notice.

          TTY            Prints the terminal characteristics for  this
                         terminal.


     Terminal Characteristics Arguments

     In addition to the above arguments, you  can  use  the  following
     arguments  to  INITIA  SETTTY  in your SWITCH.INI file.  They are
     effective for any job that is logged in.  Most of  the  following
     arguments  are  equivalent  to  an argument to a SET TTY command.
     Many of the arguments can be  preceded  by  NO  and  a  space  to
     disable  the  defaults.  These are included in the description of
     the function of the arguments.

     Each argument, equivalent  SET  TTY  command,  and  function,  is
     listed below.

     Argument       Equivalent Command            Function

     SETTTY         None                Must be present for the  other
                                        INITIA  terminal  arguments to
                                        be effective.

     ALTMODE        TTY ALTMODE         Converts ALTmode codes 175 and
                                        176  to  the ESCape character.
                                        NO   ALTMODE   restores    the
                                        individual identities of codes
                                        175 and 176.

     BLANKS         TTY BLANK           Controls the output  of  blank
                                        lines.   NO  BLANKS suppresses
                                        the   output   of   automatic,
                                        consecutive  carriage  returns
                                        at the end of output.

     CRLF           TTY CRLF            Controls     the     automatic
                                        carriage  return and line feed
                                        at the  end  of  the  terminal
                                        line.   NO CRLF suppresses the
                                        automatic carriage return  and
                                        line feed.

     DEBREAK        TTY DEBREAK         No longer supported.

     DEFER          TTY DEFER           Suppresses echoing to a  video
                                        terminal    until   input   is
                                        requested.   NO  DEFER  allows
                                        characters typed to the system
                                        to be echoed when the terminal
                                        is idle.

     DISPLAY        TTY DISPLAY         Notifies the system  that  you
                                        have a display terminal.  This
                                        characteristic can be used  by
                                        programs  that  control output
                                        to the terminal.

     ECHO           TTY ECHO            Controls   echoing   to    the

                                        vertical tab  characters.   NO
                                        FORM  instructs  the system to
                                        output the line-feeds.

     GAG            TTY GAG             Controls  the   reception   of
                                        messages  sent  with  the SEND
                                        command.    NO   GAG    allows
                                        messages when your terminal is
                                        at user level.

                                        access types.  REMOTE  is  not
                                        recommended    for    use   by
                                        non-privileged  users  because
                                        it  can only be reversed by an
                                        operator [1,2].

                                        terminal  to  xxxx baud.  This
                                        construction  sets  the  input
                                        and   output   speeds   to  be
                                        equivalent.

     SSIZE:n        TTY [S]STOP n       Sets the page length  of  your
                                        terminal.   This  controls the
                                        number  of  lines   that   are
                                        output to your terminal before
                                        an automatic stop.

     SSTOP          TTY SSTOP           Ignores CTRL/Q until output is
                                        stopped  either  automatically
                                        by the system,  or  by  CTRL/S
                                        from the user.

     STOP           TTY STOP            Stops output to  the  terminal
                                        automatically    after    page

     SYSDPY         None                Runs   the    display-oriented
                                        SYSTAT    program    that   is
                                        appropriate   for   your   set
                                        terminal type.  SYSDPY is only
                                        valid in  the  SWITCH.INI  and
                                        TTY.INI files.

     TABS           TTY TAB             Informs the system  that  your
                                        terminal  has tabular ability.
                                        NO TABS instructs  the  system
                                        to simulate tab stops.

     TAPE           TTY TAPE            Turns on the XON (CTRL/Q)  and
                                        XOFF  (CTRL/S)  keys for paper
                                        tape reading.  NO  TAPE  gives
                                        CTRL/Q and CTRL/S their normal
                                        function.  TAPE  is  discussed
                                        in  the  TOPS-10 Monitor Calls
                                        Manual.  For more  information

     TERMINET       None                Sets   tab   spacing   for   a
                                        TERMINET-300.

     TYPE:xxxx      TTY TYPE xxxx       Informs the system  that  your
                                        terminal is of the type xxxx.

     UC             TTY UC              Changes  all  the   characters
                                        input  from  your  terminal to
                                        uppercase.

     WIDTH:xxx      TTY WIDTH xxx       Sets the width of the line  on
                                        your     terminal    to    xxx
                                        characters.

     XMTSPEED:xxx   TTY SPEED nnn xxx   Changes the  output  speed  of
                                        your  terminal.  This argument
                                        affects the speed at which the
                                        monitor  sends  characters  to
                                        your terminal.

     The arguments listed above are described more thoroughly  in  the
     description of the SET TTY command.

     Terminal Attributes Arguments

     The following arguments to INITIA SETTTY set up the attributes of
     your  terminal.   Like  the  preceding  terminal  characteristics
     arguments, you can use the following arguments in your SWITCH.INI
     file.

     Unlike  the  terminal  characteristics  arguments,  most  of  the
     following  terminal  attributes  arguments do not have equivalent
     SET TTY commands.  The exceptions are DISPLAY, ISO, EIGHTBIT, and
     OVERSTRIKE.

     To display your current terminal attributes,  you  must  use  the
     command INITIA ATTRIBUTES.

     To set terminal attributes, use the following command format:

          INITIA SETTTY arg arg ...

     All the following arguments can be preceded with NO and  a  space
     to disable the setting.
