Re: [Plug] Modem lost! Puzzledly!


Before I make any suggestions for getting your modem working under 
windows again I'd like to bring up a couple of things.

Most newer modems support PnP and hard jumper setting.  When you buy a 
modem make sure it supports both.  I prefer to always set the modem to
com 2 (cua1) and interrupt 3.  I know Windows tells you that may cause
a problem, but I don't take Microsoft's advice very seriously.  The
advantage of doing it this way is that the modem works correctlly in
both Windows and Linux (I have been dule booting for years).

This leads to my next point... why don't you use the PII for all of
your OS needs?  The obivious is that you can't run both at the same 
time.... well, still run Linux on the other box, you can't have too 
many Linux boxes, but even one Windows is too many!

Ok, now... that said...  You didn't say which version of Windows you
are using.  I noticed that 98 insists on an inf file for modems where
as 95 is a little more flexable.  Try deleting the old modem settings
and reboot windows.  It should detect the modem and ask you to
configure it.  Did you get through all of this yet?
