I don"t know which cell phone models are compatible, so report me if you know.
One user report that RTS of PL2303HX is at pin 3. At this scheme pin 2 used
Small comment. This schematic is basically designed for the PL-2303H and is compatible with PL-2303HX. The most important thing is that, though the input pads have 5V tolerance, the output pads are decided by VDD_325 (pin 4) which is driven by VO_33 (pin 17, +3.3V).
