The 16550 costs all of $13, and makes a : big difference. Don't get the Hayes card... the 1k buffer won't be used (and : IMHO isn't needed). I'm running an ESP card on my BSDI machine with patches to enable the 1k buffer. I got rid of the spurious overruns while running my momde at 115,200. It also seems to get me a little perfomarnce boost when using the net with a heavy CPU load and bi-directional traffic.
