Terminal Manager and VTE Windows

1.1 QUIT ENDS ALL CONNECTIONS
   Complete your work before using either the Terminal Manager Quit or
   Remote Session Manager Quit. Both Quits are intended to return the
   terminal to its initial state at the end of a work session.

1.2 TERMINAL MANAGER - CREATE
1.2.1 CREATE LAT X SESSION
   Session Manager and VMS
   A problem can occur where a user cannot log into an X session on a host.
   The terminal can still open VTE windows and pull down menus. The
   watch cursor replaces the pointer.
   If you have this problem, enter the command:
   $ SHOW DEVICE TWA
   If the host show a device number over 999, reboot the host. This action
   will restore the VT1200’s ability to create X sessions.
   To obtain a patch that permanently corrects this problem, contact your
   Digital representative.




                               Terminal Manager and VTE Windows 1–1
1.2.2 TCP/IP X SESSION
    Remote Pause Unsupported in UWS V2.1
    A difference between UWS V2.1 and UWS V2.2 prevents the successful
    return from a Remote Session Manager Pause state in UWS V2.1.

1.3 TERMINAL MANAGER - CUSTOMIZE
1.3.1 CUSTOMIZE SECURITY
    TCP/IP BIND Name Service needs Names in Security
    The Security authorization for TCP/IP requires that you only use decimal
    dot notation (123.45.67.89) for the IP address of a remote system needing
    access. However, if a BIND Name Server is available on the network and
    it knows about the remote system, then you must use the name of the
    remote system (eg, node.building.institution.area).

1.3.2 CUSTOMIZE HOST AND PRINTER PORTS
    Use Speed 19200 or 38400, not both
    Due to a hardware limitation in the communications circuits, the speeds
    38.4Kbaud and 19.2Kbaud are mutually exclusive. All other speeds may
    be mixed between the two serial ports, but only one or the other of the
    two top speeds is available at one time.

    Diagnostic Port supported on Printer Port
    When this mode is enabled, a printer attached to the printer port will
    print out all messages that are displayed in the Terminal Manager
    Message Region as they are received. You can control the messages that
    are printed by selecting the appropriate message types in the Customize
    Terminal Manager dialog box.

1.3.3 CUSTOMIZE LAT
    Software Update required for multiple Ethernet adaptors
    If your system has multiple Ethernet adaptors to allow simultaneous
    access to separate LANs, contact your Digital representative for an up-
    dated copy of DECW$LAT_TRANSPORT.EXE. The new version provides
    support for multiple link definitions.




1–2 Terminal Manager and VTE Windows
1.3.4 CUSTOMIZE FONT PATH
   Must Quit to Reset Font Path
   Once a session makes use of the fonts, you can view the font path, but
   you can’t change it until you quit out of the Terminal Manager. This
   applies to all sessions including VTEs. The VTE does not require a font
   path but will use host-based fonts for character and line attributes if
   available.

   Link lost to font server requires quit to reset font path
   If your link to the font service is disconnected, perhaps due to the font
   server node shutting down, or due to a network problem, you will get
   a message in the Terminal Manager window message area stating (for
   example):
   Session n to NODENAME terminated. Link lost with remote node.
   Font path to node NODENAME lost. Reestablish font path before
   starting X sessions.
   Even if your other sessions to other nodes are still active, you need to
   reset your font path to continue working. This is because the behaviors of
   applications running on the terminal are not predictable when a request
   for a new glyph or font fails. Therefore, you should close all sessions
   and quit the terminal manager to restart the terminal and reset the font
   path.

   Font compiler needed for non-DECwindows environments
   If your VT1200 application requires fonts that are not in the DECwin-
   dows library, you will need to get a font compiler to convert the fonts you
   have to a format the VT1200 can use. A compiler is available through
   the Internet that will convert the standard .BDF interchange format of
   most fonts to the .DWF format of the VT1200.
   The pcf font compiler is available on gatekeeper.dec.com in the
   /pub/DEC/VT1000 directory. There are two files in that directory:
   README   pcf.tar.Z
   The README file contains:




                                Terminal Manager and VTE Windows 1–3
    The file pcf.tar.Z in this directory contains the contents of
    the contrib/server/pcf directory that is on tape4 of the MIT
    X11R4 distribution. This code should allow you to build a
    bdf->pcf compiler so that fonts can be generated that are
    compatible with the VT1000 series terminals.
    (Note that DEC’s .dwf format is also supported by the VT1000.)
    and the pcf.tar.Z file is a compressed tar file containing the source code.
    To retreive it via the internet, copy the files from:
    gatekeeper.dec.com:~ftp/pub/DEC/VT1000
    If you cannot copy from the internet, contact your Digital representative.

1.4 VTE - CUSTOMIZE
1.4.1 CUSTOMIZE GENERAL
    Answerback only supports printable characters
    Unlike the VT320, you cannot put control characters like CR or ESC into
    the VTE answerback message.

1.4.2 CUSTOMIZE 7-BIT NRCS
    Choose NRCS to Match Keyboard
    When using a VTE with a non-US Keyboard and 7-bit NRCS character
    sets, you must manually use the VTE Customize 7-bit NRCS Selection to
    choose an NRCS set to match the current keyboard language. Select the
    corresponding language if you use a typewriter layout. Data Processing
    keyboards in any language require the ASCII (North American) NRCS
    set. This is a 7-bit issue only.

1.4.3 CUSTOMIZE PRINT
    VTE Printer Modes are user settable
    Printer Modes are user settable from the Customize dialog box as well as
    host settable by control functions. The buttons in the dialog box display
    the mode that was set from either source.
