Here is the back story: As Intel turns the wheel of technological evolution, embedded customers are dragged along, often kicking and screaming. The ADLE3800PC incorporates the Intel Atom® E3800 Series SoC. This is the smallest Atom package that Intel has released. It allows for better use of space on a PCB since the chipset features, CPU and GPU all reside within a single BGA. It boasts impressive performance numbers comparable to Intel First Generation Core® products. With this massive integration of functions into a single chip, some features are scaled back or eliminated in the name of forward-thinking high speed interface technologies. The E3800 Series does away with LPT, Keyboard/ Mouse, but retains features like GPIO and RS232 COM ports. The RS232 COM ports are supported with a reduced signal and instruction set designed to leave just the basics in place. The reduced signal set is as follows: Supported Interface Signals: Tx Rx CTS RTS The command instruction set is also reduced. The following commands are not supported by the Windows 7/8 HS-UART Driver: IOCTL_SERIAL_SET_WAIT_MASK IOCTL_SERIAL_GET_WAIT_MASK IOCTL_SERIAL_WAIT_ON_MASK IOCTL_SERIAL_XOFF_COUNTER IOCTL_SERIAL_LSRMST_INSERT IOCTL_SERIAL_SET_BREAK_ON IOCTL_SERIAL_SET_BREAK_OFF Provided that an application does not require a full set of modem control signals, and none of the commands above commands are used in existing applications. The COM ports will work successfully. Please consult the “ISG_BYT-I_HSUART_Driver_Release_Note” included with the driver download for detailed information about the HSUART driver. Thanks! Karim.
