Serial port selection with io.openport

I've got a USB-to-serial device as that's currently identified as /dev/ttyUSB0. How do I open a connection to this device with io.openport? The file at https://files.unipi.technology/s/public?path=%2FSoftware%2FMervis%2FExample projects%2FCustom serial protocol shows that I need a definition in the format 'serial:6:9600,8,N,1'. I'm guessing the '6' is identifying which serial port to open, but where is that number mapped to a device?
sorry!! This is not mentioned anywhere (will write it in the step by step) this is Mervis internal mapping.... The numbering is following:
- USB1-USB4 - 10-13
So USB1(as labeled on the case) has ID 10.
