Each port is individually configurable as to speed, base address and IRQ setting. The use of jumpers means that it is easy to set and install.

1 out of 5 eggsNot as described

Pros: Did get 2 port serial card, but not ISA

Cons: Ordered 2 Cards. Receieved a different item inside each box. Both cards were for a PCI slot, not ISA. Probably a problem with the supplier, as the Box indicated ISA as well.
