drivers to translate the USB signal into a serial communication line that radio software can understand. Chelegance Driver Specifications & Requirements Most modern LD-C101 cables utilize the FTDI (Future Technology Devices International)
When you connect the LD-C101 cable to a computer running Windows, the operating system needs a "driver" to understand how to communicate with the FTDI chip inside the cable. Without the correct driver, the computer will not assign a COM port, and software like WSJT-X, HRD (Ham Radio Deluxe), or FLDIGI will not communicate with your radio.
