You don't technically need to go into Windoze to get the settings. If it's
not PnP, you just set the jumpers properly. If it is, you'll probably need
to use isapnptools anyway, and that _can_ be done without reference to
Windows at all (pnpdump --config is good, but make sure the serial ports
aren't in use.)

Some new modems can be configured with jumpers to be either PnP or
non-Pnp. For example, the 3com Model 5687-03 i bought a few weeks ago. I
chose to specify IRQ and serial (COM) port with the jumpers, so i wouldn't
have to make a new isapnp.conf...
Also, before this, you may need to use setserial to tell the kernel which
IRQ and port address the modem is using. In my case, i put the modem on
IRQ 5, and the default for ttyS2 is IRQ 4, so i had to reconfigure that.
Also, i had to tell bios that IRQ 5 was used by a "Legacy ISA" card before
Linux could contact it...

i used wvdialconf to find the modem and make sure it was working, and to
get a good init string. But if i use wvdial to try dialing in, pppd dies
complaining the remote computer needs to provide a secret password or
somehting like that. Since pon works fine, i just use that.
