The setup for using the simulator is described on the libdivecomputer website 
[1]. The socat tool works on Mac OS X too, although you may have to compile it 
yourself. The pre-compiled simulator binary you can download from the 
libdivecomputer website too [2]. Last but not least, you'll need to compile the 
libdivecomputer library with the "--enable-pty" option (this replaces the patch 
that is mentioned on the website). This last step is important because without 
this option libdivecomputer will fail when talking to a pty instead of real 
serial port.

Once you have everything, you start socat and the simulator:

socat PTY,link=/tmp/ttyS0 PTY,link=/tmp/ttyS1 &
./simulator -p /tmp/ttyS1 -b <backend> <filename>

In subsurface you use /tmp/ttyS0 as the serial port, and you can "download" the 
data from the memory dump into subsurface.

Note that for several backends the simulator does not only need the memory dump, 
but also auxiliary *.header and *.systime files. Those have to be created 
manually from the logfiles generated by the libdivecomputer test apps. I can 
help with that if necessary.
