Not sure where the previous post was CC'd to per se, but take a look here: http://www.watson.org/~robert/freebsd/portmaster25/ A couple of other comments: - Some Intel motherboards include BIOS revisions that have errors regarding the configuration, or at least, are incomprehensible. We had to futz for quite a long time to get it working for the netperf cluster. Unfortunately, I seem to have misplaced the instructions -- I can only advise trying counter-intuitive things. I think the problem was that the BIOS was referring to 1/2 and meant A/B, or said A/B and meant 1/2. - On some motherboards, the RTS/CTS seems to flip too frequently for the Portmaster 25, which detects this as a wiring problem. I had to turn off flow control on the port, set "hangup off". Otherwise, I saw the serial console disconnect a few seconds whenever the test started moving fast.
