Because of the way ISA handles interrupts, it is not possible to reliably share interrupts among multiple cards. However, if all the ports are on the same card and the card is designed properly, then the ports can be shared (this assumes the device driver knows how to deal with this). If you want to use all your com ports, there is no reason why you can't use interrupts other than 3 and 4 by cutting the leader to the appropriate pin and soldering a wire from there to the interrupt line you want to use. It's really quite simple and I have it working on my machine. If you want more information on this then please email. Also, if you decide to do this and fry your board then don't blame me. ------------------------------------------------------------------------------ Jason J.
