What is a USB to Serial Converter?
A USB to Serial Converter is a converter used to connect a device with a USB interface to a device with a serial port (such as RS232, RS485, or RS422). This converter is widely used in the communication needs between modern computers and traditional serial devices, especially when many modern computers are no longer equipped with traditional serial ports.
