Serial Ports are a common way to communicate with devices. The most common serial ports, as used by devices like Metex/Voltcraft multimeters, are RS-232 interfaces.
RS232-USB Converters
To operate devices having RS-232 interfaces on computers that have only USB interfaces available, RS232 to USB converters are available. Many different chipsets exist that have slightly different properties, often supporting only a subset of what common UARTs like the 8250/16550A can do. Please note that a driver for the respective operating system is required (sometimes included in the OS already, e.g. mostly for Linux).
Common chipsets are:
