Although RS232C requires both positive and negative voltage levels, neither a microprocessor (with the addition of an external device such as MAX232) nor any other chip will have great difficulty in conforming to the specification.

All USB-to-RS232C cables I've seen (quite a few actually) were OK. If you have to worry, it is about your peripheral, assuming you would venture to design and build one yourself.

The (MAX232) drivers provide RS-232 voltage level outputs (approx. ± 7.5 V) from a single + 5 V supply via on-chip charge pumps and external capacitors. That is what one source of information has on the subject.

End of story. The sequel is on Google.
