 * This test is used to check that the serial output of the firmware
 | 
						|
 * (that we provide for some machines) contains an expected string.
 | 
						|
 * Thus we check that the firmware still boots at least to a certain
 | 
						|
 * point and so we know that the machine is not completely broken.
