Add an RS232 serial port to your system using an available USB motherboard header

 The USB to RS232 Serial Adapter lets you add an RS232 port to any desktop system that is equipped with an available USB motherboard header.
 Unlike standard USB to serial cables, this cable is designed for use inside the PC case, affording an entirely internal solution with no mess or   extra adapters needed.
 This compact and simple USB adapter offers a cost-effective solution that bridges the compatibility gap between modern computers and legacy   serial peripherals.
 

 Features
 Supports COM port retention
 Bus-Powered – no separate power supply or battery required
 Single chip USB to asynchronous serial data transfer interface
 UHCI/OHCI/EHCI host controller compatible
 USB 2.0 Full Speed compatible
 Synchronous and asynchronous bit bang interface options with RD# and WR# strobes
 FIFO receive and transmit buffers for high data throughput.
