Running out of ISA slots?

One DSerial-550 doubles the serial ports in a system short on ISA slots. In addition to solving ISA real estate shortages, the board is ideal for systems where manual setting of IRQ and COM addresses is a must.

The DSerial-550 offers a generous selection of IRQ and COM settings, to minimize the possibility of conflicts in resource allocation. The DSerial-550 is ideal for any serial peripheral.
