getAvailablePorts static method

Future<List<SerialPortInfo>> getAvailablePorts()

Returns all serial ports currently available on this device.

The implementation is platform-specific:

• Windows — reads HKLM\HARDWARE\DEVICEMAP\SERIALCOMM from the registry.
• Linux — scans /sys/class/tty for ttyUSB*, ttyACM*, ttyS* entries.
• macOS — scans /dev/cu.* (call-out devices only).
• Android — queries connected USB serial devices via the USB Host API platform channel; returns usb:-prefixed paths.
• Web — returns a single synthetic "Web Serial Port" entry; opening it shows the browser's native port-picker dialog.
