Fascinating. This means, then, that the "media filter" adapters we use
at work to plug an RJ-45 UTP connection into the old IBM PS/2s'
token-ring cards would have a male DE-4 connector on the computer end,
being the size of what's commonly known as a DB-9 connector, but with
only four pins?
Your friend and mine,
