 Greg,
      I am able to send data bytes properly.One problem, I am currently facing is to
enable Address parity and Data parity.

For Address parity we have to give a mark parity ( 0x04 ).
For Data parity we have to give a space parity ( 0x05 ).
I don't know how I can enable parity in pl2303.c.

plz help me.

Thanks,
 Raj
