Thanx for the test.

Infact you can set the devicename in PD with the  

  "devicename /dev/tty.USA19H2b2P1.1"
as message within PD.

Since this is a hack the first try to open a comport will fail on load and 
report an error, just ignore.

If you can send the makefile extnension, I will check it in.

it is welcome, If someone wants to clean the the external so it can figure out 
the the devicenames (eg. for os-x) at startup and index them, this would be 
great.
