I'm having trouble figuring out what this device is. I picked it up about
4 years ago from a computer show. I didn't put much thought into it when I
purchased it - just thought it was a bluetooth controller in the
CompactFlash form factor. Now that I'm actually trying to "use" it,
it turns out it may not really be a controller. Here's a blurry picture of
it (sorry camera can't focus): http://i26.tinypic.com/2ajumjb.jpg

From the top down it says:
Pretec
Pocket PC
Expansion Pack
Bluetooth
CompactBT(tm)

When I plug it into any Linux laptop with a CF to pcmcia adapter, I get
this returned:
ttyS01 at port 0x02f8 (irq = 3) is a 16C950/954

Is this some kind of pass-thru device? Meaning ttyS01 somehow gets bonded
to a physical serial port (ttyS0) so that other, external devices can use
this laptop's serial port to talk with other instruments.

Any ideas?

It /appears/ to be a "Bluetooth" serial port. Data written to this serial
port is transmitted via Bluetooth radio to a receiving Bluetooth device
(like your cellphone or your PDA). Data transmitted from outside Bluetooth
devices (again, like your cellphone or PDA) can be read from the serial
port.

It looks like the Linux kernel recognized the serial port, so you should be
able to use one of the Linux "Bluetooth management" suites to manipulate
the connection. Congratulations: you now have a way to sync your PDA or
phone with your Linux computer.
