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 the default Com 6), please use the Lava Com Port Redirector Utility. This program will allow you to change the numbering of your ports without changing I/O address resources.
Interrupt Resources may be modified for the LavaPort Parent device (see Device Manager - Multi-function Adapters), but not for individual ports because all four ports on the LavaPort-Quad share one IRQ. Please note that interrupt changes require a reboot to take effect.
