DTECH USB to Serial Adapter Cable 16 ft DB9 Male RS232 to USB Cord

Bottom line: The DTECH USB to Serial Adapter Cable 16 ft DB9 Male RS232 to USB Cord: Genuine FTDI FT232 chipset, not a clone that fails Windows driver checks; main trade-off: DB9 male end only, so male-to-male serial devices need a null modem or gender changer.
