Doing a little more investigation, I found a library that sends/receives
data over a socket connection using rfcomm.

However, if I use the client side of this library, doing a connect to
another bluetooth device that implements the Serial Port Profile, it
works beautifully, I'm able to send data that gets displayed on the
windows side hyperterminal.

When I try to run the server side library on the Linux machine, and
attempt to make a connection over the hyperterminal, I get an error
message: "Connection attempt failed because the remote device does not
support the Serial Port Profile".

How do I get a listener on a Linux host to accept serial port profile
connections?

this step is not needed at all.

You might wanna use "rfcomm --raw connect 0 1".

No. The baud rate is for the physical interface of the module and not
the RFCOMM connection.
