The global configuration in the "Comet Default" document is saved when you quit Comet. 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 faster on older Macintoshes but may prove incompatible with some displays. If you have a color or greyscale display which you've configured to run normally with many colors or shades of gray, dataComet will automatically change the screen mode to black-and-white when fast drawing is enabled and the session does not have color drawing enabled in the "Control Color" dialog, and back to normal mode when you switch to another window, so that monochrome and color sessions can run on the same screen at maximum speed.
"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.
"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.
"Remap Option key-combinations": Changes the keyboard layout to the "Comet Keyboard--no diacritics" keyboard layout, which disables the standard mapping of Option-E, I, N, and U (or other keys in non-US keyboard layouts) to characters with diacritical marks so that Option works properly as a Control key and macros are triggered immediately by these key-combinations. The "Comet Keyboard--no diacritics" keyboard layout must be installed in the System for this to work.
"Quit automatically when all windows closed": Quit the application when there are no open windows.
"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.
MacTCP/OT bug- workarounds
"Use Asynchronous sends": This option causes MacTCP to send multiple packets rather than send only one at a time (and wait "synchronously" for the packet to be ACKed before proceeding, so that the Macintosh performs no other normal processing while the network and remote host pass the data packet over the network). This is the default, but NOTE MacTCP may prove unreliable on LocalTalk when this mode is enabled using versions of MacTCP prior to 1.1.1.
"Send only one packet at a time": This option causes MacTCP to send multiple packets on a connection rather than just one at a time . This is the default, but NOTE that MacTCP may prove unreliable on LocalTalk when more than one packet is sent asynchronously on a connection, especially on 3270 connections. If your connection hangs, try disabling this option.
"Use TCP Status calls": Open Transport (as of 1.0.7) does not perform MacTCP status calls correctly. This must be enabled to get statistics and/or push the MacTCP timers.
"Push MacTCP timers": MacTCP has traditionally set the TCP re-transmit time-out to unreasonably large values. Enabling this option resets the timers to more reasonable values, which provides much more responsive performance over connections with high packet loss rates (which are usually caused by a lossy physical connection or an overloaded gateway). You must enable "Use TCP Status calls" for this to take effect.
File Transfer options
"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.
"File transfer--archive overwritten files in ".back"": This option automatically appends the contents of a file to "filename.back" before the download commences and overwrites the file.
"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).
