The application i have is one in which i want to use 4 serial ports and may be simultaneously..
This could go upto 8.
Is there any hardware card which can help me do this. Conceptually i am told that there are only two interrupts which can be used for the serial ports
i.e. IRQ 1 & 4 are the same and IRQ 2 & 3 are the same and cannot be used simultaneously. Will this kind of a card along with the drivers be available anywhere .. where can i get it..
