[Rack] minotaur serial ports

[Jake]

so, before Minotaur was taken apart and replaced, there was a USB to 
serial adaptor connecting to the RFID reader.  It was a keyspan.

I think now it's being used to connect to a soekris thing.

so i grabbed another USB to RS232 thing from mischief but it doesn't seem 
to work... and i'm not sure where all the other ones went.  does anyone 
else have one they can bring in?  Or can i try switching with the soekris 
thing?
