Menu-key equivalents are superseded by macro keys, but the menus are not corrected.
The Print command, which uses QuickDraw printing, does not space characters correctly when the Comet-fonts are used to print foreign language characters, and will not use the Comet-fonts with Background Printing unless they are installed in the System.
Some Macintosh configurations (such as those using an E-Machines display board) may "hang" soon after Comet opens its first session windows if fast drawing mode is enabled. This occurs due to incompatibility between the display adapter and the fast drawing mode. To fix this problem, you can reconfigure your Comet Default document by launching Comet, cancelling the initial Configure Session dialog, turning off "Enable fast drawing" in the Control Global... dialog, and pressing the Save button and then the OK button.
If you try download a file to a locked disk, after the file transfer fails you will not be able to access that particular file again until you quit and restart Comet; you will not be able to completely dismount the disk because the file will be "busy", although you can eject the disk, unlock it, and access other files.
Nota Bene: The MacTCP driver interface can have asynchronous sends enabled; in this mode, Macs using MacTCP up to 1.0.2 on LocalTalk will be prone to crash (with the cursor frozen and the whole machine hung). You can configure this option in the Global Configuration dialog.
Those using Ethernet should enable asynchronous sends, because there is a major drawback to using synchronous sends: until the host acknowledges that it has received the data you have sent, the Mac will seem to "hang." Although the mouse cursor will move, the Mac will not respond to mouse button-downs or keystrokes until the acknowledgment is received; in the event of a communications problem with the host, this can leave you hanging for minutes! If this occurs, you should NOT reboot your Mac, but should wait for the send to either complete or abort.
(In general, it is desirable to have asynchronous MacTCP sends enabled, and to have the fast-drawing option enabled if your monitor runs in Black and White rather than Color or Greyscale mode, which is configured using the Monitors Control Panel device; due to the possibility of encountering the rather lethal problems discussed above, these options are disabled in the default configuration. When using the Configure Global dialog, "OK" the new configuration without pressing the "Save" button when you first try these options; you can "Save" the configuration later after verifying that it works correctly.)
System 7.0 notes: Color performance under System 7.0 is known to be very slow due to changes in QuickDraw under System 7.0. Using color under System 7.0 may also produce drawing outside the emulator screen area if the background color is not White. In addition, producing the keys Option-E, -I, -N, and -U will require additional keystrokes unless you install the "Comet Keyboard-No Diacritics" Keyboard Resource provided with Comet by dragging it into the System Folder, since Apple has modified its key-mapping calls to ignore this resource unless it is installed in the System.
Fixes to 2.1.3 Beta 2 in 2.1.4 (2.1.3 has been skipped):
* Errors no longer occur when saving configuration
files.
* 3270 Start Field commands now update the screen
display correctly when they replace an existing
field marker.
Fixes to 2.1.3 Beta in 2.1.3 Beta 2:
* You must now close a session before reconfiguring
it using the Reconfigure Session... dialog.
* When "Open document once only" is modified, the
document status is updated immediately.
* TFTP reports errors correctly when writing the
last block of a file causes a disk-full condition.
Fixes to 2.1.3 Alpha in 2.1.3 Beta:
* When printing 3270 screens with Courier on a
LaserWriter, NULL characters on the screen now
appear as spaces rather than carets.
* Comet now handles MacTCP Domain Name Resolution
properly when the host entry has been cached.
* IBM 3270 terminal reconfiguration is now performed
when a session is reopened, and screen garbage no
longer appears when the 3270 is made larger.
* Setting colors in the Color... dialog no longer
crashes under System 7 with TuneUps installed.
* The Comet TFTP file transfer server now recovers
properly from errors, and no longer presents errors
dialog when routine file transfer errors occur.
Fixes to 2.1.1 in 2.1.3 Alpha:
* Aztec's latest C compiler provides compatibility
with 32-bit mode for this new release.
* ASCII terminal sessions now reliably erase all
lines of the last screen from a previous session
when a new session is opened.
* Printing uses Courier except when Comet-fonts are
needed to represent special characters; printing
can be configured to always use Courier (using the
Control Global... dialog).
* The Word Select macro used to handle double click
word selections now breaks the selection at the
beginning and end of a screen line.
* Documents can be configured so they can be opened
only once using the Control Session option "Only
one session per document." Clicking on a document
which is already open will bring that document to
the top and re-open the session if it is not already
open, rather than opening another session. (This fix
provides better support for Cornell's Bear Access).
Enhancements in 2.1.3:
* Comet registers an AppleTalk entity with the type
COMET, so that network administrators can easily
check user's Comet versions and configuration.
* The Session dialog now offers an option so that
Comet will connect with hosts which do not send
a log-on prompt or other data to indicate that
Comet's terminal-type setting is acceptable.
* Automatic cursor positioning can be disabled with
a key macro command ("!Ct").
* Serial baud rates of 57.6K and 38.4K are offered.
* You can create a sound resource using "Record
Beep..." in the Control menu. This sound will be
used as the bell for that session when its window
is not in front. This function is available only
on Macs equipped with microphones; other Macs using
System 6.0.4 or higher can use the sound. "Delete
Beep" is provided to delete your replacement beep.
* Files downloaded using Comet are made TeachText
documents by default. A "Set default file type"
dialog in the File menu allows you to select
an application or document of the type you wish
to use as the default.
* A key macro command to make the next keystroke
a Meta-key has been added ("!CM").
* A file downloaded with the string ".print" in its
name will be printed automatically. If the name
contains ".nodialog", no Print Dialog will be pre-
sented; if the name contains ".delete", the down-
loaded file will be deleted after printing.
* A <Control-L> character entered in the .edit
window will cause a page eject when printing.
NB: Other applications may not handle this ASCII-
standard control character correctly.
* An iconified window which receives data will beep
as well as become highlighted.
Fixes to 2.1 in 2.1.1:
* IBM 3278-3 & -5 emulations did not always correctly
report the status of the first field on the screen.
* Printing the emulator screen (as opposed to the .edit
window) no longer crashes on Macs (e.g., the Mac +)
without Color QuickDraw when using System versions
