I have a similar situation in that I have an internal on one of my machines. I set the IRQ on the _modem_ to IRQ 5 and left the kernel config alone. works fine with cuaa2 for dial-out and ttyd2 for dial-in. You now have two uarts responding to the interrupt request and confusing the kernel. Try the -c option at the boot prompt and disable sio1 -- it may work. Better, though, to reconfig the kernel to IRQ 5 and set your modem to respond to IRQ 5. -- Jay On Tue, 8 Apr 1997, Christopher J.
