You should be able to use the V24 module for the RS232.

I used to do quite a lot of RS232 programming about 20 years ago, but I've
forgotten it all and no longer have the books, but it was quite
straightforward under DOS using INT 14h or something like that. Modula-2
systems also had good facilities using coroutines if you wanted to do
asynchronous comms.

I don't know anything about Bluetooth, but if I wanted to write a Blackbox
module to deal with it, I'd model it on CommStreams and / or V24 to keep it
simple.
