Serial port mapping

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/Y/X, where Y is the number of section, and X is the number of the serial port. X and Y are counted from 0.

USB converters (FTDI, CH34x, PLxxxx and CPxxxx) are also supported by default. For using other gateways or devices, installation of drivers is necessary.

USB2 /dev/serial/by-port/1
