Subject: [PATCH] Added support for Linux in the SerialCom.py connection
 function The connect would previously only work immediately preceding a
 download (on Debian Jessie). This was solved by connecting first with rtscts
 enabled, which triggers something to allow messages to be received. I think
 the board is being reset on each connection, this is a workaround.
