Explanation

Ultralightweight laptops are compact and sacrifice legacy ports to save space and weight. RS-232 is an older serial interface that modern laptops do not natively include. A port replicator (or docking station) expands a laptop's connectivity by adding legacy and additional ports-including serial RS-232-allowing the device to be connected. A USB-C cable alone cannot bridge a USB-C port to an RS-232 device without conversion. Wi-Fi Direct and Hotspot are wireless technologies and are irrelevant for a wired serial device.
