Low Latency: (930 based Edgeport only) Normally the UART will interrupt when the receiver has been idle for 4 character times. (For example 4ms at 9600) As long as data is being received the UART will continue to buffer them until its internal FIFO is full (~56 bytes). This flag causes the Edgeport to poll the RX FIFO for received bytes. If any bytes are available they will be sent to the driver without any delay. Remap Baud: (All operating systems - 930 and TI based Edgeport) Setting the

Here is a comment from the code: If the receiver is active then do not complete this read. The problem is that the Edgeport buffers the RX bytes and we poll the driver. If we do not receive any bytes in 200ms we may report an erroneous event even if there are available bytes in the Edgeport device or driver. • Test Ports - Perform a confidence test on the internal workings of the serial ports. • Power Management – Turn on and off the power for HubPorts with USB PlusPower ports Edgeport

Advanced Tab The Advanced tab allows you to do the following: • Uninstall the drivers. • Enable Event Logging – Place event messages in system event log. • Configure how COM ports will be assigned. The driver supports COM port number assignment in two ways: 1. Assign COM ports based on converter serial number. This is the default setting. In this mode, the driver uses the serial number of each converter to uniquely identify it, and the COM port assignments for a given converter are bas

Understanding Hubs Hubs, critical components in the USB architecture, are wiring concentrators that enable the attachment of multiple devices, thus converting a single attachment point into multiple attachment points. USB architecture allows a cascaded multiple hub configuration with certain power limitations (explained later in this section). See figure 1.
