Prolific PL2303 USB-GPIO

PL2303HXD / EA / RA has 8 software controllable “General Purpose Input Output, GPIO” control signals pin, you can use this API to control -direction: input or output-logic level: high or lowGPIO Pin define:1. GP02. GP13. GP24. GP35. GP4--RI (*)6. GP5--DCD(*)7. GP6--DSR(*)8. GP7--CTS(*)(*): In general, serial port control input signals
- CTS, DCD, DSR and RI are used as MODEM control signals , However, if the MODEM control signal are not needed, these signal could be used as general-purpose input/output signal(GPIO)You can download the source code from Prolific web-site, and then develop your own android applicationRequirements: --------------------
