New Revision: 257446
URL: http://svnweb.freebsd.org/changeset/base/257446
Log:
Allow the Arduino Leonardo to work by supporting CDC=0 devices.
CDC=0 simply means "no command codes", CDC=1 means "AT command codes."
There's no driver change required! It's purely to tell the application
layer whether to speak AT commands or not. Things are all still serial.
