I'm not familiar with the Pactor so I may easily be missing something. But have banged my head
against enough walls with serial
connectors in the past decades, almost enough (almost) to appreciate USB instead. USB is great when the magic works, but COM ports
still have the mixed advantage of needing no magic software
, just a human to flummox around the connection options. Never, with peripherals or mainframes or networks, saw two COM ports used for one connection. I would guess it is possible to design a system where two separate ports were used for full duplex. IIRC Pactor is akin to the NATO STANAG(?) equipment
and if you add "military" "NATO" and "German engineers" into the pot...anything goes.
Still...I'd bet someone there can reply to email
in Colonial. When I need to gamble on that, I usually send a machine translation (Babblefish or Google) along with my email
question, noting that it is just that, and the same tools often produce a useful translation if the reply isn't clear.
Either way, the BT issue and the, ah, unique dual COM port business, should be unrelated. Perhaps. Maybe there's a Pactor user group on Yahoo or someplace that can give you some insight?
