[----------]

   Until the fancy UART interface chips came out (8251, etc.), they were
just glorified parallel to serial (serial to parallel) converters, generally
one of each on the chip with two parallel ports and two serial ports.
You might try looking up some of the older UART parts (1602, AY-5-1013,
or whatever), and seeing how they look.
