These values will remain in the EEPROM when the board is off and can be retrieved later by another sketch. EECON1 EECON2 eedata eedath eeadr eeadrh eedata Register Hold-bits data for readwrite and Eeadr contains the address of the EEPROM memory location to be reached. You must notify us of any billing issues or discrepancies within 90 days of first appearing on your billing method. This can be done from within Windows using a tool I found on but the only premise is that the drive is already recognized as a PL2303 USB to serial converter.
