If your DEC-Talk doesn't respond, check the following:

Insure you've used the installation utility that comes with your
synthesizer to install the low-level drivers that DEC-Talk requires.
You should be able to tell if the low-level drivers are properly
installed, because DEC-Talk announces "DEC-Talk Ready" when you first
start your computer.

If you are using the DEC-Talk2 card with Windows95, make sure you
follow the card installation directions that came with your
synthesizer or use the information below provided by DEC.

If you are using DEC-Talk Express, you will have to disable the serial
port to which the DEC-Talk is connected before you run any DOS
applications.  Go to the control panel to accomplish this.  You may
require sighted assistance--some users report machine hangs when trying
to disable a port that is in use by the DOS mode drivers, and they must
first temporarily remove the DOS mode drivers from the autoexec.bat
file, turn off the port in Windows, then re-enable the DOS mode drivers.

DECtalk PC and DECtalk PC2 Windows 95 Install.

The following procedures should be followed to install the DECtalk PC or
DECtalk PC2 in a PC running Windows 95.

1. Before the board is installed in the PC do the following:

A. From the Windows 95 START menu select Settings/Control Panel
B. Double click on the "Add New Hardware" applet.
C. This will start the "Add New Hardware Wizard" dialog box, press the
   Next button.  
D. Select NO  to the question "Do you want Windows to search for your new 
   hardware?" and press the Next button.
E. In the "Hardware Types" window, scroll down to the "Sound, video and 
   game controllers" type, click on it to highlight it and click on the 
   Next button.
F. At the next screen, click on the "Have Disk" button.
G. Insert the DECtalk Intallation disk into the diskete drive, "A" or "B". 
   Make sure the drive designator is shown in  the "Copy manufacturer's 
   files from:" window and click on the "OK" button.
H. You will then be presented with the "Select Device"dialog box. Select
   either the DECtalk PC or DECtalk PC2 whichever is appropriate. When it 
   is highlighted, click on the "OK" button.
I. After a short delay, you will then be presented with the Input/Output 
   Range that the DECtalk can be set to and not interfere with other devices 
   in the system.
J. Either click on the "Print" button to print the selection or write down 
   the I/O address setting info e.g., 0250-0257. 
K. Click on the "Next" button  and at the next screen click on the "Finish" 
   Button.
L. You will now be prompted to shut down your machine.  Click on the "Yes" 
   button.
M. Turn off your machine when it says it is ok to do so. Remove the power 
   from the PC and take the cover off so that the DECTalk PC can be installed.
N. Set the switches on the DECtalk board to coincide with the I/O address that 
   had been resereved for the board in the previous steps e.g., 250. Please 
   refer to Section 3 of the User Guide for switch setting specifics.
O. Install the board in an available ISA slot in the PC, put the covers back 
   on, re-attach the power cord and restart the system.

Checking the resources reserved for the DECtalk board.

The resources reserved for the DECtalk board can be checked by doing the 
following:

A. From the Control Panel select the "System" applet and at the "System 
   Properties" dialog box select the "Device Manager" tab.
B. Scroll down the device list to the Sound, Video and game controller 
   entry and double click on the icon or single click on the box with the 
   plus in it.
C. Click on the DECtalk entry to highlight it and click on the "Properties" 
   button at the bottom of the dialog box.
D. In the DECtalk Properties dialog box, click on the Resources tab. You will 
   then be presented with the Input/Output Range resource settings the system 
   is reserving for the DECatlk board.
E. Make suer that the first number of the resource setting matches the I/O 
   address setting on the DECtalk board e.g., 0250 Resource setting = 250 I/O 
   Address setting.
F. If they do not agree, then the board switches should be changed to match
   the system settings.

Eliminating conflicts between DECtalk Express driver and Windows

OVERVIEW:

If you want to use the DECtalk Express TSR driver with Microsoft Windows
applications, or in a DOS box under Windows, you will need to prevent Windows
from taking over the serial port that is connected to the DECtalk Express. This
is done by creating a small text file and editing DTEXP.BAT to use DEBUG
(provided with MS-DOS) to delete the serial port (and the port that shares the
same interrupt) from the BIOS Equipment table. You will also need to check your
SYSTEM.INI file for Windows to verify that there are no conflicting COM port
assignments.

NOTE: If your system does not use the standard address and IRQ assignments for
its serial ports, DO NOT ATTEMPT TO USE THIS METHOD.

NOTE: Once this modification is performed, the COM port to which the DECtalk
Express is connected will "disappear" as far as most software is concerned.
Also, the port that shares the same IRQ (if it exists) will also disappear.


Procedure:

1. change to your DECtalk Express directory (typically C:\DTEXP)
2. make a backup copy of your DTEXP.BAT file
	COPY DTEXP.BAT DTEXP.BAK
3. using your favorite TEXT editor, add the following line to your DTEXP.BAT
It should go just below the dt_driv line.

   If your DECtalk Express is connected to COM1 or COM3:
       DEBUG < C1C3.DBG
   If your DECtalk Express is connected to COM2 or COM4:
       DEBUG < C2C4.DBG
4. change to your Windows directory (typically C:\WINDOWS).
5. Make a backup copy of your SYSTEM.INI file
        COPY SYSTEM.INI SYSTEM.BAK
6. using your favorite TEXT editor, search the SYSTEM.INI file for any
   instances of the line COMxBASE (where x is '1' and '3' if your DECtalk
   Express is on either COM1 or COM3, or x is '2' and '4' if your DECtalk
   Express is on either COM2 or COM4.) Delete these lines.
