serial-port enables access to a specific serial port. This interface is restricted because it provides privileged access to configure serial port hardware.
The slot is intended to be implemented by a gadget snap and is not provided by the core system snap.
Should specify a single path attribute:
path(slot): path to serial device node e.g.
Or three attributes:
usb-vendor(slot): integer representing the USB Vendor ID, must be in range 0 < vid <= 65535
usb-product(slot): integer representing the USB Product ID, must be in range 0 <= vid <= 65535
path(slot): path where a symlink will be created to the device e.g.
Snaps that want to consume a serial port use
plugs: [ serial-port ] with the serial port to connect specified during interface connection. Available serial ports for the system can be seen with
snap connections. Once connected, the consuming snap can use the device via the path specified by the connected slot.
