- A possible fix for that would be to set the jumpers on the second board to use
- different IRQ's, if possible. Some allow you to select virtually any unused IRQ
- for each COM port.

- Well, if you use Win95 software, it shouldn't care what COM port your modem
- uses. It should just give the data to the OS and let it sort it out. Else, why
- would Windows have to know what COM port the modem is on? If you're using all of
- this top-notch hardware, you should be able to afford new, Win95-logoed SW.
