[lug] Partitioning and modem problems

[Mike McCallister]

A little more info that may well point in a good direction. I 
double-checked the COM port that Windoze says the modem is using. Device 
Manager reports the modem is on COM5. So I booted back to Linux and tried 
to run setserial again (BTW, it's truly wonderful that it remembers my last 
command even after logging out!!), changing ttyS2 to ttyS4 to reflect the 
"new" port. Setserial reported there was no such port (as ttyS4/COM5?).

I then rechecked /proc/ioports. I had earlier written down that 
proc/interrupts called the device using IRQ9 as usb-uhci. Well, 
proc/ioports notes that the usb-uhci device is using ef80-ef93. Meanwhile, 
lspci says the modem is using IRQ9 and I/O ports at dfe0. So, something 
tells me that there is either a conflict, or the modem port is not set 
properly. Is this right?

Thanks yet again!
