What a waste. Buy an multiport shared interrupt serial card instead. http://www.byterunner.com sells an 8-port version for about $150 and a 4-port version for about $75. They work with FreeBSD and the stock SIO driver. >But he is unsure that it is that simple in FBsd UNIX. The SIO man page explains how to set up a multiport shared interrupt card like the ones byterunner sells. It's a hard read at first, but I can send you a sample kernel config if you can't go it alone with the man page. John
