As very option is a cable USB, with emulation...

With PL2303 or other controller...

Very fast and full functionally on this device.

Pc side pin 2 - rx, pin 3 - tx ,pin 5 gnd. we need level shifter because from pc rx and tx voltage swings between +/- 9v and phone can not handle it (phone hardware will damage) level shifter changes this to ttl level (voltage swings between +/- 3v .I am giving most popular schematic here or you can use any usb to phone cable.you can find many pin outs at pinouts.ru.
