The LGE CDMA USB Serial Port Windows driver is a driver used for enabling communication between a LG CDMA device (such as a mobile phone, modem, or other LG CDMA-compatible hardware) and a Windows computer over a USB connection. The "serial port" aspect refers to how the device communicates with the computer as if it were a traditional serial communication port, often used for data transfer, diagnostics, or communication with software that interacts with the device.
