Non-intelligent cards usually come in two varieties, one using standard com port addresses and use 4 IRQ's, and another that's AST FourPort compatible and uses a selectable block of addresses and a single IRQ. (Addresses and IRQ's are set using setserial.) If you're getting one of these cards, be sure to check which standard it conforms to, prices are no indication.
