Dear all,

I am currently working on a proxy program on ubuntu, which do both
receiving packet from and sending packet to Riot OS  (Riot Mote is a
samr21-xpro board connected to the Ubuntu pc via USB port). I run into the
following problems:

1. Is there a way I can send packet from Ubuntu to RIOT via USB port? Any
related library and example will be appreciated.
2. For receiving a packet at Ubuntu,  currently I understand I can write a
script to extract the information in the debug message. Is there a more
standard way to do that?

Also I have some issue with pyterm the node. After successfully "make flash"



I can not access the node via pyterm:
sudo pyterm -p "/dev/ttyACM0"

2015-11-23 23:13:14,061 - INFO # Connect to serial port /dev/ttyACM0
Welcome to pyterm!
Type '/exit' to exit.

Any idea? The debug light flash as the same frequency as the warning
information.

Thanks
