It is an intelligent card which does not use multiple 16550s. It runs each port at up to 115200 and uses a single irq for all 8 (or 16 on a 16 port board). I've found that if the machine crashes, the 16550 AST clones I'm also using are not guaranteed to come up with a warm boot - need power cycle to flush buffers or something. With the cyclades I have no such trouble. Danny
