1 yes but have a schematic and source hex for pic18f4550 based usb rs232 converter and it is possible tu use a sampe max232 for usb rs232 converter if i need only txt rxt and gnd pinout and what is the driver and schematic
MAX232 is a level converter. it is just covert RS232 level to TTL and you need either an FT232 or an USB enabled PIC like PIC18F2450 for usb interfacing as said by FvM.
