All well > and good, but in use, com3 stops com1 working and com4 stops com2. This is definatly a IRQ conflict problem. COM1 and COM2 are normally at IRQ3 and 4, so you need to reconfigure your card to use different IRQs for COM3 and 4. Go in the the Windoze 95 system menu and look at the hardware's IRQ usage. Pick 2 that your new card can support (usually they are something like 5, 7, 9, or 11) and switch to them. 4 ports are really great for development work. I have an ICE on one port, a modem on another, another talking to the device being emulated and another port monitoring a seperate serial bus. One big problem with win95 is that it doesn't like to have the mouse on anything but COM1. I have some DOS serial code that only supports COM1 or COM2, so I have a hard time running win95 at the same time .
