"ttyY" notation specifics

...

1. Linux virtual tty (switchable by alt+F1 - atl+F12 on a text console) – are represented as "/dev/tty<N>" where N is from 0 to 11. Those tty devices must be free from the Linux "getty/mgetty" and similar programs (specified in "/etc/inittab")
2. Onboard serial lines are represented as "/dev/ttyS<N>" where N is a number. For example "/dev/ttyS1"
3. Proprietary (depending on a driver) devices are represented as "/dev/tty<XXX>" where XXX is a complex letter/number notation. For example "/dev/ttyR01" is the first port of a MOXA card and "/dev/ttyaa" stands for the first port of a DIGI card.
