What's the "RS" in RS232/RS485/RS422?
The RS stands for Recommended Standard. Nothing really agreed upon or official. At least not
in the sense of the "made-by-committee" standards like IEEE-1284 and IEEE-1394.
What does this mean? Because RS standards are merely recommended and technically general,
lots of manufacturers develop products that are at best inferior. They cut corners and cheat in
order to manufacture cheaper products
