Dos6.22安装软件,现在使用Dos的朋友不是很多了,希望能大家一些方便.

in the upper left-hand corner of the screen whenever a sound
is emitted.  The other option is to flash or blink the screen
whenever a sound is emitted.

The visual cue and the screen flash cannot both be active at
the same time.  (It doesn't do any good to display the visual
cue while the screen was blanked - you wouldn't see it.)

When using the visual cue option, sounds produced by computer
programs will display a single "musical note" or visual cue
in the upper left-hand corner, provided the sounds are long
enough in duration to be detected by AccessDOS.  However,
When the sounds are generated from within AccessDOS itself, a
second character will appear next to the musical note to give
you some information about the type of sound.  An up-siren
produced by AccessDOS, for example, will show a musical note
with an up-arrow next to it.  (See manual.)

The "musical note" or visual cue is not compatible with all
applications.  Do not use the "musical note" or visual cue
with PC Paintbrush or Lotus 1-2-3 (TM) while running either
application with a color monitor.  You should not use the
"musical note" visual cue when in the MS-DOS 4 Shell.
It is also not compatible with applications that produce more
than one screen of information simultaneously, such as split
screens in text editors.  The "musical note" or visual cue
may work in some parts of programs while not in others.
For example, the visual cue does not work with the document
viewer or equation editor in WordPerfect, but works well in
the word processing portion of WordPerfect.  The "musical note"
or visual cue may also encounter trouble with some CGA monitors.

In general, the screen flash or blink is compatible with more
software applications and monitors.  However, the screen
flash or blink feature is dependent on the video hardware,
and may not be compatible with all monitors.  For example,
some AST VGA cards are not compatible, nor is the PS/2 Model
25/30 with the 8086 processor.


6. SERIALKEYS NOTES

SerialKeys is a very special function which allows you to use
a communication aid or other special input device instead of
the computer's standard keyboard or mouse.  To use
SerialKeys, you would connect your communication aid or
interface to the computer's serial port.  SerialKeys then
transforms input to the serial port into keystrokes and mouse
movements.

To use SerialKeys, your computer must have a serial port
available.  The computer's standard keyboard should also be
connected to the computer.  Also, if you want the SerialKeys
program to provide mouse functions, you must have a
compatible mouse driver loaded in your computer.  This
usually means that you must also have a mouse connected to
your computer (see MouseKeys discussion above).  Some older
(pre-generation 3) Microsoft mice will not work with
SerialKeys.

SerialKeys is designed to allow the user to provide input via
a special aid connected to the computer's serial port.
However, SerialKeys does not disable the standard input
devices such as the keyboard and mouse.  If another computer
user chooses to enter input at the keyboard while someone is
using SerialKeys for access to the same computer, key states
such as the CAPS LOCK, SCROLL LOCK OR NUM LOCK may get out of
synchronization between the keyboard and the computer.
Likewise, if another user operates the mouse while someone is
moving the mouse cursor via SerialKeys, the mouse cursor will
get out of synchronization between SerialKeys and computer.

Some applications do a lot of processing of the input they
receive from the keyboard.  If you are running SerialKeys
with these types of application, you may lose keystrokes or
characters in transmission, even at a slow baudrate.  First,
try slowing down your transmission speed or baudrate to see
if that improves the problem.  Second, limit the number of
characters you send per a single selection on your aid.

SerialKeys may not work on some applications on older IBM
computers (PC, XT, and AT), especially if the
application is designed to only retrieve keyboard information
when a key is pressed.  On these computers, SerialKeys places
the keyboard character it is trying to emulate into the same
buffer the keyboard would put a character except that the
application will not read the buffer because you never
actually pressed a key on the keyboard.  One such software
program is Microsoft Works.  One solution is to run MS-DOS
version 4.0 or above and run the program "keyb.com" prior to
running AccessDOS and SerialKeys.

Moving the mouse with SerialKeys assumes the mouse is
operating within an application which allows the mouse to
move equally in both the horizontal and vertical directions.
If you experience problems moving the mouse cursor with
SerialKeys, especially when you move large distances or move
quickly between the same two locations, the mouse driver
software may be the cause.  Many mouse drivers contain a
"threshold" speed, beyond which the mouse cursor movements in
the horizontal and vertical direction no longer correspond to
the resolution or "mouse scaling" used within the
application.  Please refer to the mouse driver software
manual if you need to turn this feature off.  Another
solution is to limit the size of your SerialKeys mouse
movements such that you never exceed this "threshold".

RUNNING SERIALKEYS WITH WINDOWS

The SerialKeys feature in AccessDOS only works within MS-DOS.
However, if you would like to use SerialKeys with Microsoft
Windows 3.x, there is an access utility for Windows 3.x which
also contains a SerialKeys function.  (See Windows discussion
above.)

If you want to run SerialKeys in both AccessDOS and Microsoft
Windows 3.x, you need to do two things.  First, you need to
have both AccessDOS (to give you SerialKeys in MS-DOS) and the
Access Utility for Windows 3.0 (to give you SerialKeys in
Windows).  Next, you need to set some special AccessDOS
command line switches.  These switches, which are best placed
in a "batch" file (see below), are only needed if you want
SerialKeys to function in both AccessDOS and Windows.  The
SerialKeys function in AccessDOS and in the Access Utility
for Windows are the same, so once you program your
communication device, you will be able to work in either
operating environment.


BATCH FILES FOR RUNNING IN WINDOWS

Batch files can be created in MS-DOS, and are typically used to
execute a series of commands by entering a single
instruction.  A batch file is easy to recognize, since it
should always have a filename followed by the three character
extension, "bat".  The easiest way to create a batch file is
to use a word processor which has the capability to read,
write, and save a "text" or "ASCII" file.  If you are
attempting to run SerialKeys in both AccessDOS and in Windows
while in standard mode, you should create a batch file with
the following three commands:

     ados /skw
     win /s
     ados /ske

An example of a working batch file that was placed in the
"c:\ >" root directory follows.  It assumes that AccessDOS
was stored in the MS-DOS sub-directory and that Windows was
stored in another directory.  You may need to change the
directory paths to match your own computer setup.

     c:\dos\ados /skw
     c:\windows\win /s
     c:\dos\ados /ske

Remember, you will need to have Access Pack for Microsoft
Windows (see discussion under Operating Systems) in
order to run SerialKeys once inside Windows.  Also note that
your AccessDOS "saved settings" file, which is called
"ADOS.CFG", should have SerialKeys saved "on" prior to
running this batch file (see manual for discussion on how to
save settings).

NOTE:  If you do not intend to run SerialKeys inside of
Windows, you should not ever use these special command line
switches.

ADVANCED SERIALKEYS NOTES

SerialKeys was designed to automatically lower the
transmission or baud rate to 300 baud, any time 3 consecutive
characters are received with data transmission errors.  This
is an important feature when SerialKeys is used in a
multi-user environment.  It can however, be a nuisance for a
single user, especially if they are having problems with
their communication aid.  If you are using SerialKeys as a
single user, you may want to disable this feature of
SerialKeys.  To disable this automatic baudrate lowering or
"reset-on-error" feature of SerialKeys, use the special
command line switch "/sks" along with "ados" when you load or
install AccessDOS.  For example, to start AccessDOS with the
"reset-on-error" feature disabled and for a color monitor,
you would use the following instruction:

     ados /c /sks

NOTE:  This special command line switch can not be saved in
the "ADOS.CFG" file, so if it is useful to you, you will have
to type it each time you start up your computer to run
AccessDOS.  You should not use this special command line
switch if you are not the only person using SerialKeys on a
particular computer.



D. MISCELLANEOUS

It is recommended that you store AccessDOS (ADOS.COM,
ADOS.OVL, and ADOS.CFG) on your computer hard disk in your
MS-DOS sub-directory or on your floppy disk which contains MS-DOS.
While this is not absolutely necessary, it reduces confusion
since most MS-DOS computer users have a directory for all their
MS-DOS utilities and a MS-DOS "path" command to find their MS-DOS
utilities.

When AccessDOS is loading, it will make an attempt to
determine your computer speed (actually CPU speed) and set
counters for the various beeps AccessDOS produces based upon
that speed.  If you have a computer which has multiple
speeds, you should load or install AccessDOS while the
computer is at the speed you intend to operate AccessDOS.
Changing speeds while AccessDOS is running may cause the
beeps produced by AccessDOS to become unrecognizable.

On some computers, the sounds made by AccessDOS (and other
programs) may be less audible, due to the design or placement
of the speaker.

AccessDOS is not compatible with most terminal emulators,
such as the IBM PC 3270 (TM).
