Those boxes have a lot of electronics inside them, basically one FPGA
that is programmed to do all the conversion.

No, it's not even close. This would be like transplanting a dog's
head on a human being. It takes a good bit of glue logic, and I
suppose you could build all the glue yourself with TTL but you'd wind
up with a big expensive box full of stuff.
What is wrong with the USB/RS-232C interface boxes that you don't like?
Can you just put a serial card in your machine?
