4. The LavaPort-Quad hardware appears in Device Manager in two places: under the Multi-function Adapters tree and as part of the Ports tree. Please note that any changes to the Resources (I/O Address & IRQ) used by any one of the four ports on the Lava Quattro-PCI must be made through the Resources page of the appropriate LavaPort-Quad PARENT - not through the individual Ports pages. Modifying I/O Address and IRQ Resources is NOT recommended. 7

The LavaPort-Quad hardware appears in Device Manager in two places: under the Multi-function Adapters tree and as part of the Ports tree. Please note that the Resources (I/O Address & IRQ) used by the LavaPort-Quad can only be modified through the LavaPort Parent device - listed under Multi-function Adapters. Modifying I/O Address and IRQ Resources is NOT recommended. If you wish to change the Com number of either one of the ports on the LavaPort-Quad (e.g. Assign Port 1 to be Com 3 instead of t

Changing the Com numbering of your Ports Unless you already have more than 4 Com Ports installed in your PC, Windows will by default configure the LavaPort-Quad ports as Com5 through Com8. If you wish to change the Com number of any one of these ports (e.g. Assign Port A to be Com 3), please use the Lava Com Port Redirector Utility included in the “Utils“ subdirectory of your Lava Installation Diskette.This may be necessary because some communications applications programs do not recognize Port

Setting LavaPort Data Rates in Windows The data rate of the LavaPort may be set using the Bits per Second pull down menu. Please note that this menu will also appear when setting the “Port Properties” in any communications application, and may have to be set independently of your Control Panel settings. Control Panel settings may not necessarily be linked to those of your Communications Application. For example, Port speeds in Dial-Up Networking are controlled independently of speed settings in

ページ16に含まれる内容の要旨
Each of the LavaPort-Quad’s four ports incorporates a 64-byte FIFO (first- in-first-out) buffer. The FIFO control tabs set the buffer “trigger” levels.When the buffer is filled to its trigger level with the selected number of bytes, the CPU will be interrupted and asked to either reload the buffer (for transmission), or retrieve data from the buffer (for reception). Most efficient data transmission occurs when the CPU is interrupted infrequently. For each interrupt, the CPU can then service the

Setting LavaPort Flow Control in Windows Flow Control refers to the type of signaling that is used between the modem and the LavaPort. If you are connecting the LavaPort to a modem or ISDN terminal adapter, use the default setting of Hardware (RTS/CTS) flow control. Software Flow Control (Xon/Xoff ) is used only for connecting the LavaPort to a non-modem serial device (e.g. Using a null-modem cable to connect to another Com Port). 17

Lava Modem Speed Set for Windows The LavaPort-Quad supports data rates up to 460.8 kbps, including 115.2 kbps and 230.4 kbps. However, not all modems support Com Port rates above 115.2 kbps. If your modem does not support higher data rates and you select a higher data rate in the LavaPort Properties, Windows will automatically default to the slowest supported rate in the chain. Some modems do support higher data rates but require special settings (AT Commands) and INF files for configuration. La
