- While this suggestion will work in some->many situations, it is not a
- good generic solution due to the variability of hardware. There are
- three situations that will cause this to fail - 1) a video card that
- interferes with Com4; 2) a motherboard that will not release used IRQs
- to the bus; 3) an internal modem with a weak IRQ driver. The best
- solution is to disable Com2 or to install the new modem as Com3 on an
- unused IRQ. More info is available in our technical note "Diagnosing
- Serial (Com) Port Problems" from our web page below.
