USING THE CONTROL GLOBAL DIALOG

    To save the global configuration in the Comet Default document, you must press the "Save" button.  When using the Global configuration dialog to "Enable fast drawing" and "Use Asynchronous sends with MacTCP", "OK" the new configuration without pressing the "Save" button, so you can test these options before permanently configuring them.  If you find that Comet tends to crash on launching, try throwing out the Comet Default document in the System Folder. 

   "Enable fast drawing":  Let the application try to use the direct-to-screen drawing mode, which is very fast but may prove incompatible with some displays.  If you have a color or greyscale display, your "Monitor" control panel must be set to "Grays" and "Black and White" before Comet can run in this mode.

   "Restrict fast drawing to topmost window":  Let the application try to use the direct to screen drawing mode with multiple windows.  This mode may produce some odd screen displays if windows overlap, so if you see characters appearing in inappropriate places on the screen, check to see that this mode is off; if it is, then you might try disabling direct-to-screen drawing entirely.

   "Quit automatically when all windows closed":  Quit the application when there are no open windows.

   "Use Asynchronous sends with MacTCP":  This option causes MacTCP to send multiple packets rather than just one at a time.  This should be the default, but MacTCP may prove unreliable on LocalTalk when this mode is enabled.

   "Reset emulator selection range after Copying":  When this option is on, a Copy, Save, or Append command will reset the selection range to no selection, so the whole screen becomes the default selection range for the next Copy, Save, or Append.  If you want the selection to remain fixed on the screen so you can the same selection on successive screens, turn this off.

   "Always use Courier font when printing with a LaserWriter":  This option allows you to configure Comet so that it will always use the resident LaserWriter Courier font when printing; this saves the time it takes to build the Comet fonts and get better justification of columns; with the Courier font, however, the NOTIS library foreign character set will no longer print as you see it on the screen.  If this option is not selected, the Comet fonts will be used whenever special characters appear in the text to be printed, and Courier otherwise.

   "File transfer--always do dialog to rename files":  Before transferring a file, Comet will present a Standard File dialog allowing you to select (upload) or rename (download) the file.  This is off by default.

   "TFTP Server On":  Comet offers a TFTP server for use in transferring files.  TFTP is the Trivial File Transfer Protocol, which you can invoke on the host to which you are connected to start a file transfer.  Comet also offers a "download" command to transfer files.

   "Request approval of TFTP transfers":  If this is on, when the TFTP server receives a request to transfer a file, it will query you.  Note that if the TFTP server is on and Server asking is off, someone could transfer files from your computer without your knowledge (although they would have to be able to specify the names of the files they wished to transfer).
