 2015-08-24 15:05:03 -05:00
Ed Gonzalez edd809c269 Look for end bits in voice frames too. 2015-08-21 08:16:06 -05:00

Ed Gonzalez 2f828cf2ac Handle ThumbDV being unplugged gracefully. 
When the ThumbDV is unplugged the serial read thread stops and tries to re-connect. All writes to the serial port also stop.
