3.2.2 Changing Resource Settings with Device Manager

The DSP-100's serial ports are addressable in two modes: block mode, and “COM”
mode (see Chapter 5: Hardware Information). The DSP-100 is addressable in either
mode from Windows 95.

1. Start the Windows 95 Device Manager.

2. Double click on the hardware class Multi-function Adapters to list

hardware devices in the class.

3. The DSP-100 “parent device” belongs to this hardware class. The device

name for the DSP-100 is Quatech Inc-PCMCIA Dual RS-232 Serial Port
Card.

4. Open the Properties dialog for the DSP-100 device, then click the Resources

tab to view the Input/Output Range and Interrupt Request resource
allocations.

5. Several predefined Basic Configurations have been included for the

DSP-100. The table below defines the various configurations. When the Use
Automatic Settings
check box is enabled Windows 95 will attempt to
configure the DSP-100 in the order listed.

* Indicates “COM” mode addressing. Addresses 3F8/3E8 are the standard addresses for
COM1/COM3. Addresses 2F8/2E8 are the standard addresses for COM2/COM4. All other basic
configurations use “block” mode addressing at non-standard base addresses. Windows 95
enumerates any COM port at a non-standard address starting with COM5.
