Hello Hendrik,

we can also address the port by their USB specific information (e.g. the serial number of the device instead of just 'COM<something>' (which is cumbersome especially if there are many devices connected).

when you use the standard driver 'ftdi_sio', 'udev' will automatically create symlinks below /dev/serial/; in the directory /dev/serial/by-path/ you'll find symlinks named after the topology ("where is the device plugged in"), and in /dev/serial/by-id/ you'll find symlinks named after the product name and serial number ("which device is it").

HTH,
cheers
