Axon serial port maps

See the table below to find out how the physical RS485/RS232 serial port lines are mapped into Linux ports within /dev/.

Alternatively, all serial ports with N (eg. /dev/ttyNS0) mentioned below are also accessible via /dev/extcomm/X/Y, where X is the number of Group, and Y is the number of the serial port.

All those ports are also accessible via Group number 0 in /dev/extcomm/0/Z.
