Can I ask what you were doing that needed more than two serial ports? Especially "every PC in the office". I can see a few special purpose computers. But I can't imagine a use case for having them in every PC.
You put one into each of five computers, then you arrange them in a pentagram, with ten null-modem cables.
Then you write software to make your net work. Or summon the dark overlord.
