- This is basically what I found out. I did have AUTO_IRQ enabled
- in the kernel, but for some reason, it wasn't picking up the IRQ correctly.
- I had the IRQ set at 2, with the 'addresses' set at 2a0->2b8(?), but
- the IRQ that the kernel was finding was 5 :( What I ended up doing was
- just changing the IRQ to 5, and I seem to be having at least hard-wired
- communications.
-
- Now, to get the modems to work :)

- Thanks loads...
