The Serial Adapter /Serial Converter - Generally

A serial adapter, also referred to as a serial converter is a small electronic device which can convert one type of data signal into a different type of data signal. The difference between an adapter and a converter generally is that an adapter usually only adapts the physical interface of a device to match a different type of physical interface of a different device whereas a converter converts the actual data stream between two devices. Therefore we will use the term 'converter' in the following.

Even the RS232 standard is an older communication protocol it is still used by many modern devices in both business and consumer markets and is also often used for personal and office devices. Actually many new devices designed today are designed with a RS232 serial port, often because RS232 is a very robust and reliable protocol which is fairly easy for program writes to integrate into their system.
