this is for bluetooth devices that use rs232 as transport. this
includes external rs232 dongles and some older pccard device (i.e. i
have xircom cbt).

yes, i think you are talking about serial-port-profile dongles. pair
of those would essentially replace null-modem cable. they are
different, as they run a simple application on them that implements
serial-port-profile. usually, it is not possible to use serial
interface to talk to bluetooth device itself (i.e. send hci command
etc.).

it should be possible. i just tried to see if my xircom pccard would
work and it did not :( basically uart(4) did not attached the card :(
