--- Comment #58 from Fred Wright <fw at fwright.net> ---
One thing I haven't seen mentioned in this thread is that the DEVICEMAP keys
are *volatile*, which means that adding them manually only lasts as long as the
current incarnation of wineserver.  Obviously the best solution is for
wineserver to create the keys when it starts up, but in the meantime, the
options are:

1) Launch wineserver with -p, then edit the registry.

2) Leave regedit running (after making the edit(s)) until the serial
application is launched.

3) Create a wrapper that keeps wineserver up while making the necessary
registry fixes and running the application.

I've implemented #3 as a Python script, which I'll upload.

The application I'm using only seems to care about the values, not the value
names, so I elected to derive the value names from the actual device names, but
with a bit of "Windowsification".  E.g., "/dev/cu.XXX" -> "\Device\cu.XXX". 
Actual Windows systems have names of the form "\Device\Serial0",
"\Device\BthModem0", etc., which are somewhat less informative.

I've tested this with SXBlue Config running under Wine 1.62 on OSX 10.9.1.  It
also has code to perform the equivalent setup for parallel ports, but that's
untested.
