  NAME

    visit - Runs XNS-based remote login command

  SYNOPSIS

    visit [-p protocol] [option ... ] [host]

  FLAGS

    -p protocol   Defines the protocol to be used for the current session.
                  The valid protocols are xt and vtp.  The default protocol is
                  xt.

    The following options can be used for all protocols:

    -e char       Specifies an escape sequence to access interactive mode.
                  The chars parameter specifies a sequence of characters, with
                  a circumflex (^) representing <Ctrl> and a backslash
                  followed by a circumflex (\^) representing the circumflex
                  (^) character.  <Ctrl-Y> <Ctrl-Y> is the default escape
                  sequence.  To prevent escaping to interactive mode, a null
                  escape sequence may be specified (such as -e "").  This is
                  useful for captive accounts.

    -f logfile    Specifies a log file on the local machine.  If the specified
                  file does not exist, it is created.  If the file exists, it
                  is overwritten.

    -i time       Specifies the time (in 1/60-second intervals) visit checks
                  for terminal input.  The default is 5.

    -n            Ignores the login script .rloginrc.  However, default visit
                  connect options in the login script are not ignored.

    -q            Prevents the display of certain visit messages.  These
                  messages include the XON/XOFF message that appears during a
                  visit connect and the termination message.  This option is
                  useful for cosmetic purposes in shell scripts that invoke
                  visit.

    -r            Sends a <Return> to the remote host after a connection is
                  established.  This option can be used if the remote host
                  does not automatically prompt the user to log in.

    -s baudrate   Sets the terminal baud rate for the visit session.

    -w            Stops visit from waiting for input from a device attached to
                  an auxiliary port.

    -x            Causes the local system to interpret XON/XOFF, or <Ctrl-S>

                  and <Ctrl-Q> flow control.  This is the default if the local
                  terminal is set to ixon (see stty(1)).

    -y            Allows XON/XOFF, or <Ctrl-S> and <Ctrl-Q> to be passed to
                  the remote host instead of being interpreted by the local
                  system.  This option is useful when running programs on the
                  remote host that need to interpret the XON/XOFF character
                  sequences.  For example, the emacs editor uses <Ctrl-S> as a
                  command.  The -y option is the opposite of the -x option.
                  The -y option is the default if the local terminal is set to
                  -ixon (see stty(1)).

    -?            Displays a usage message and exits.

    The following options can be used with the XT protocol:

    -o          Prevents the connection to the remote host from being
                terminated on logout.  To disconnect or exit from the remote
                system, enter the escape sequence in interactive mode.

    -t device   Specifies a device number (device) of the remote terminal
                device if a remote host is running CLIX.  (For example, a
                device of 5 corresponds to the terminal device /dev/ttn05.)
                If the device is preceded by a plus sign (+), a getty process
                is not started.

                If a remote host is an Intergraph VAX/VMS system, an XT device
                name becomes associated with the logical name device.

    The following options can be used with the VTP protocol:

    -c           Configures a Communications Server.  Only the superuser can
                 execute this option.  No other options should be specified
                 with this option.

    -l port#     Specifies the port on a Communications Server for the
                 connection.

    -j address   Specifies an X.25 address to access a host on a Public Data
                 Network (PDN) through an XNS/X.25 gateway.  If the X.25 host
                 is connected directly to an XNS/X.25 Gateway, the X.25
                 address need not be specified.

  DESCRIPTION

    The visit command is a remote login command that supports the Intergraph
    Xerox Network Systems (XNS) XT protocol and the Bridge XNS Virtual
    Terminal Protocol (VTP).  Both the XT and the VTP protocols can be active
    at the same time, providing the same user interface.

    If visit is run without command-line options, the user enters interactive

    mode and a visit> prompt appears.

    Once a connection is made, an escape sequence returns visit to interactive
    mode.  <Ctrl-Y> <Ctrl-Y> is the default escape sequence.

    The host parameter specifies the remote system.  The host parameter can be
    entered as a nodename or network address.  The nodename is specified in
    the Intergraph clearinghouse (see clh(1)).  A network address has the form
    [xxxxxx.]aa-bb-cc-dd-ee-ff, where xxxxxx is an optional Local Area Network
    (LAN) number, and aa-bb-cc-dd-ee-ff is an Ethernet address.

    The visit command searches the login directory for a .rloginrc file that
    can be used to specify default options and a simple chat script.

    The following commands can be used in visit interactive mode (at the
    visit> prompt):

    ? [command]
           Displays help information for the specified command.  If no command
           is given, list all available commands.

    ! [local command]
           Executes a command on the local host.  Specifying ! alone starts a
           shell process.

    connect [option ... ] host
           Connects to the specified host.  All options described in the FLAGS
           section can be used with the interactive connect.  Each connect
           establishes a session (maximum of eight sessions).  Sessions are
           numbered starting with 0.

    disconnect session
           Disconnects session.

    exit   Terminates all connections and exits.

    help [command]
           Synonym for the ? command.

    quit   Synonym for the exit command.

    resume session#
           Resumes session#.

    show_sessions
           Lists all current sessions.

    stop_log session#
           Stops logging session#.  Logging must have been turned on by the -f
           option.

    communications problem.  Either of these messages appears only if the
    system is communicating with a remote Intergraph system and indicates the
    remote system sent an improperly formatted message.  Reboot the remote
    system.

    INC_RL, A network message was received without the end of message (EOM) bit set


    An invalid network message type was received

    The following two-line message indicates the remote system rejected the
    connection request.  If the remote system is working properly, try again
    later.  Otherwise, reboot the system.

    INC_RL, The connection request was rejected by the virtual terminal listener
    INC_RL, This generally indicates a remote system resource problem

    The following message indicates the XNS/VTP software product is not
    installed on your system.  The -p vtp option requires this software
    product to communicate with a remote Bridge Communications Server.

    INC_RL, The Bridge Virtual Terminal Protocol is not supported on this system

    The following message appears if you are not superuser when specifying the
    -c option.

    INC_RL, Insufficient privilege to perform Communications Server configuration

    The following message indicates a local system problem.  Memory could not
    be allocated for the necessary visit buffers.  Report the error to your
    local system manager.

    INC_RL, An error occurred while attempting to allocate a session control block


  EXIT VALUES
