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.

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
