Well, the goal is that no network packets can crash owserver, so let me
chase this down.
You are the world's expert on OMAP and OWFS. Are you maintaining that
adapter code yourself? Where can it be found? Perhaps, if it's ready, it can
be included in OWFS and thus track changes in the library.
You might find testing owlua easier if you try it with owserver
--fake=01,10,22,05 (i.e. simulated devices). That way you separate OMAP and
owlua issues.

I had actually tried that before, curious to what would happen
rather
than expecting it to be the answer to my question. That it did not
accept "/" meant nothing to me before, but has now allowed me to spot a
bug in my code. It now accepts "/", but I am getting a segmentation
fault in owlib instead. I have tried to trace it as best I can, but can
only get as far as the `BUS_select(pn2)' call in FS_realdir()
(ow_dir.c:459). I am not sure if it is crashing on that line, or within
the function it calls, but I cannot trace any further.
I believe this is where it calls the adaptor-specific X_select()
function. It should be calling OMAP_select() for me, but I do not
believe it is. I am calling `owopt('o', optarg, opt_server)' in my
init() function, which should set it to the OMAP adaptor. Unless there
is another step I have missed along the way.
