If EE-9s were the only non-standard serial ports I had to deal with, I
would be happy. But I've got them on DB25s, DE9s, DC37s (!) (4 poirtson
one connector..), 5 pin quincuncial DIN plugs, 8 pin DIN plugs, 8 pin
mini-DINs (and no, not the Mac version), 3-contact jack plugs, 4 pin 2mm
headers, 10 pin 2mm headers (2 different versions), 50 pin microribbons,
36 pin microribbons, various PCB card edge conenctors etc, etc, etc. But
actually, I've had many worse thigns to sort out. Mostly it's justr a
matter of matching up signals...

The first problem is that jack plugs (as we call them) tend to
monetarily short when plugged in or pulled out...
I have no idea what the flashover voltage of such a connector is, but I
am likely to measure it jsut to see...
