/dev/ttyS0 or ttyS1, ttyS2.
ttyS0 is the name of serial device on the host that is connected to the switch via a Minicom appli-
cation. The last digit represents the physical position of the serial connector on the host. For exam-
ple, if the host has only one serial connector, the device name should be /dev/ttyS0. If the host has
two serial connectors, the device name could either be /dev/ttyS0 or /dev/ttyS1, and so on.
