Maxim alone has about a dozen variations of the MAX232 (max3232 for 3v3, e.g).
It's much easier to directly go from USB to TTL/3v3 serial ports, the
basic breakout boards from Sparkfun (e.g.
http://www.watterott.com/de/FTDI-Basic-Breakout-33V) seem to be fine
and sell for ?12. Haven't used them on a C123-phone, though.
