	Notes for DOS and INSTALL.EXE
	-----------------------------

This program is for those users that either do not have card 
services or, for reasons of memory conservation, do not want 
to use card services.  This program must be run in native 
DOS.  DO NOT ATTEMPT TO USE FROM A "DOS BOX" IN WINDOWS.  
Also, this program does not work in Windows 95.

This program will create a directory called C:\TDK.  It will 
then copy file(s) from the TDKModem diskette to this new 
directory.  It will then run ENABLER.EXE and record the COM 
port setting.  The ENABLER will configure the modem for 
operation in your computer.  Finally, the INSTALL program 
will create GOTDK.BAT which will call on the ENABLER with 
the COM port already assigned.

After installing this software, you need only type "GOTDK" 
after the modem has been inserted into the PC Card slot.  
Again, this command must be issued in native DOS, not a 
"DOS Box."  

Many users like to have the modem inserted into the PC Card 
slot prior to powering up the computer.  They simply place 
a GOTDK command in their AUTOEXEC.BAT file, which will run 
automatically during the computer power-up.

	Windows 95
	----------

When the CyberExpress 3000 is inserted into the PC Card slot
of a Windows 95 computer, the computer will request the 
TDKModem diskette.  What happens is that it finds an INF file
that TDK has created for Windows 95.  This file gives Windows 
95 information regarding the modem.  This information includes 
modem features such as V.34, Class 1 and Class 2 Fax mode.  
It also provides suggested initialization strings and other 
configuration details.  Thus, the communications programs 
that interact properly with Windows 95 can obtain this 
information.  The benefit to you is that modem configuration
becomes automatic.  You will be able to install these 
programs without having to provide detailed and often 
confusing setup information.

As with any other operating system, you may only have 
one communications program using your modem at any time.  
There are several programs in Windows 95 that may try to 
have access to your CyberExpress 3000 while you are 
attempting communication with another program.  These 
programs may be loaded during startup or at a later time.
Simply switch off these programs before continuing.  Here 
are some of these programs to watch:

	Dialer
	Dial-Up Network
	Operator*

* Note:  If you have the Microsoft Unimodem V communications 
driver installed on your computer, you may have the Operator 
program automatically installed in your Startup folder.  
Since this program cannot run simultaneously with other 
communications programs and since there are currently few, 
if any, programs that are compatible with Operator, you will 
need to remove this program from your Startup folder.  It is 
probably easiest to drag this program from Startup to 
Accessories.

	UltraPort (TM)
	--------------

The CyberExpress 3000 includes TDK's proprietary UltraPort.  
The UltraPort allows the computer to communicate with the 
modem at much higher speeds than is possible with conventional 
V.34 modems.  The UltraPort is completely transparent to the 
computer and your communications software and does not 
require any special drivers.  When transferring large, 
uncompressed files to another modem, the UltraPort allows 
the computer to send the data to the modem with enough speed 
that you get the maximum "effective" data throughput.  
Overall throughput is, however, limited by line quality and 
the slowest device in the link.

The effective data throughput is the rate from computer-
to-computer.  For example, if you are sending a highly 
compressible file and your modem-to-modem connection is:
	33600 bps
	LAP-M (V.42) Error Correction
	LAP-M (V.42 bis) Data Compression
	Remote modem supports UltraPort or parallel mode

In such cases you may get an effective throughput of 120,000 
bps, 150,000 bps, or even as much as 230,000 bps.  However, 
with a conventional system, you will be limited to 115,200 
bps (57,600 bps for Apple).  

This is because the LAP-M data compression includes a 
dynamic compression technique.  It reviews the data as it 
reaches the modem and compresses it as much as possible.  
This can be as much as 10:1 compression for highly 
compressible files.  However, if your computer-to-modem 
speed is limited to 115,200 bps, then you can only enjoy 4:1 
compression for a 33,600 bps connection.  

The UltraPort overcomes this limitation without requiring 
special software.  In other words, you will reap the benefit
of the UltraPort with your favorite communications software.
You merely select 115,200 as your program's baud rate 
(57,600 for Apple) and the modem will do the rest.

UltraPort capabilities are enabled by default for sending 
files.  To enable UltraPort for receiving files, make sure 
that your comm package DTE (computer-to-modem) speed is set 
at 115,200 before making your connection.

Some software programs and some systems will not operate 
properly with the UltraPort.  If you experience unusually 
slow downloads, are repeatedly disconnected, or see numerous 
file transmission errors (excessive errors can abort a file 
transfer) your computer may not be fast enough to handle the 
incoming data.  Disconnect and try disabling the UltraPort.  
To do so, from within your comm program type:
	AT*TJ0

UltraPort will remain off until you type AT*TJ1, reset the 
modem by typing AT&F, or remove and restore power to the 
modem.
