I have one of those at home, presuming we are talking about the same thing,
a white box with four or five DB-25s and maybe a loopback connector attached
via a springy lead. This cached version of Megan Gentry's webpage describes
it as an 8-port switch...

I do not know where my file describing the command set is (it might be on
an Amiga back home), but Megan Gentry was the one who told me how it worked.
My recollection is that it's pretty simple - single, or at most double
control characters to tell it how to select the output port.
