There are two conductors for data, power and ground. There are USB

Yes, I am aware of this, so isn't the RS-232 as 2 conductors RX and TX
for data streams how ever, that doesn't change the facts that long haul
units were made implementing twisted pair balanced lines to transport
between to units and thus back into RS232 again.

You want a 'balanced RS232' ?

Use RS485.
