Windows:
The CyberExpress 5600 online help manual for Windows is loacted on your
Installation diskette. To load help on Windows 95/NT4.0 go to the START
button, then select RUN. Enter A:\HELP then press ENTER.
To Load help on Windows 3.1X/NT3.51 go to the Program Manager, select File,
select RUN and type A:\HELP.
Macintosh:
The Users Guide and Command Set reference is located on your
Installation Diskette in the file DF5600AT.TXT.

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.

------------------------------------------------------------
Apple Newton or eMate
---------------------
Installation on an Apple Newton or eMate is as simple as
inserting your TDK PC Card modem into an available PC Card
slot. The Newton operating system will recognize the card
as a communications device.
Configuring the Newton for operation with the CyberExpress
5600:
From the "Prefs" applet select "Modem" from the "Preferences"
menu. From the "Modem setup" pull down menu select "28.8 or
faster" within the selection box (do not select TDK DF2814).
Close the "Modem" menu and the "Preferences" menu.
Your modem is now setup for proper use.

UltraPort (TM)
--------------
The CyberExpress 5600 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.
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 serial data rate
and the modem will do the rest. If a program does not allow
that speed, then there is likely a good reason, like the
computer's operating system does not support a speed that fast,
or the application is older.
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.
One way to do this is to set the computer-to-modem speed to
57600 or less. If this is not possible, then change the
initialization string and add *TJ0. Or, 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.
Some systems may show serial speeds faster than 115200. However,
do not select a speed faster than 115200, since there is not a
standard method to enable these faster speeds.
The older Apple PowerBooks, such as the 1400 and 5300, allow a
serial speed of 57600 maximum, so Ultraport is not enabled. The
later models, such as the 2400, 3400, and G3, allow a maximum
speed of 115200, so Ultraport can be enabled for any applications
which support that speed.
