 * Handle (usb/serial) from console and monitored device. 
 * The idea here is to handle the incoming characters as quickly as possible. 
 * All data coming from the console or the datalogger
 * is delimited by <CR><LF>. Finding an end of line "gives" a semaphore.
 * 
 * Eventually this should be moved down to the usart interupt handlers imho
 *
 * At 9600 baud this needs to be run at least every (uart buffer size * ms) 
 * to insure that the incoming data doesnt overrun the buffers.
