Hi again.

Well.. It seems that the RXTX library in the java runtime (YAAC is a Java app)
cannot handle port names of the type:-

/dev/GPS /dev/ttyUSBGPS /dev/ttyUSB_GPS /dev/ttyUSB-GPS
(Or anything with a non numeric part after the "ttyUSB")

The requiste part of the udev rule is .. SYMLINK+="ttyUSB_GPS" for example.

The OS itself, and other app's are more than hapy to use any variant of the
above symlink names, numeric or otherwise.

But Java/YAAC IS happy with port names in the form...

/dev/ttyUSB101 (..102 ..103 etc)

Question:
Is there any compelling reason NOT to use such practices? (Faking things that
could be valid in their own right, but don't exist by default.)

Best Regards.

Dave G0WBX.

Perhaps it relies on the numeric incrementing of adding a new device of the same "nature".
