TTL to RS232 console adapter

[blood]

Has anyone made (or bought!) an adapter that takes the 3 pin TTL-level console port and converts it to a DB9 or RJ45 port that can mount in a PCI bracket? If so, what did you use? And what port did you use to power it as the console port does not provide a 3.3V or 5.5V pin for power (there is a pin labeled "RSV" which seems to supply 5V and may be usable but I don't know its capabilities).

 

I've done this before for other systems using these without too much trouble but when I tried with this board it's not working. Admittedly I haven't hooked it up to a scope to look at the signals, but I'm suspicious of the high baudrate being to blame. I have a couple USB adapters that work (so I know the console itself works), but I want to rackmount this box and wire it up to my console server. I need RS232 to do that.
