5. Click the “Resources” tab located along the top of the properties box. Confirm that the
resources Windows 95 has allocated for the DS-100 match the hardware configuration.
To modify any of the resource settings click the resource name and click the “Change
Setting” button. If the “Automatic Settings” option is selected, it will have to be
unselected to access the “Change Settings” option. This is accomplished by pointing the
mouse at the check next to “Automatic Settings” and clicking on it. Click “Cancel” to
exit without making changes.
6. If the “Change Settings” button was selected an Edit Resource window will open up.
Inside these Edit Resource windows click on the up/down arrows to the right of the
resource value. This scrolls you through all of the allowable resources for your hardware.
Pay attention to the Conflict Information at the bottom of the window. Do not select a
resource that causes a conflict with any other installed hardware. Click “OK” to save
your changes, or “Cancel” to abort.
7. The DS-100 serial ports are also listed under the group Ports (Com and LPT). Windows
95 does not assign COM1 - COM4 to ports addressed at nonstandard locations. The
DS-100 ports will be enumerated starting with COM5 (or higher) even if lower logical
numbers are available.
8. Select any of the Quatech Serial Ports listed under the group Port (Com and LPT) and
click the “Properties” button. This action opens a properties dialog for the specific COM
port on the DS-100.
9. Click the “Port Settings” tab and then click the “Advanced” button. The DS-100 driver
will display a custom Advanced Port Settings control, which allows the ports UART
compatibility mode and FIFO levels to be configured. Note that the FIFO option for each
of the two ports of the DS-100 is configured independently.
