What is the RS423 protocol?

Could you elaborate on the RS423 protocol? As someone with expertise in cryptocurrency and finance, I'm curious to understand how this protocol relates to the financial industry, if at all. Is it a communication standard specifically designed for the exchange of financial data, or does it have a broader application? What are its key features and benefits? Additionally, how does it compare to other similar protocols, such as RS232 or RS485, in terms of its performance and suitability for financial transactions?
