We started to use the serial console for debugging for the Dell PowerEdge R910 and R930, which assign `ttyS1` to the serial console on the back, as they also have, I think, a serial port on the front. Unfortunately, Linux does not allow to change the serial console port at run-time, so the set value on the Linux kernel command line matters. Most systems, including desktops, often only have one port, or the port, we are interested in, so it’s `ttyS0` in Linux. Therefore, change the default to `ttyS0` to cover more systems.
