I have a Toshiba Satellite 1805, running WXP-Home.  The modem is a standard 56k modem.
I am trying to sign on to AOL but cannot do so because the modem cannot be initialized.
The error message I am getting is that there is another device using Com1.  How do I find out what devices are attached to Com1.  Device manager is of not help.

You're so right! While technicians like me typically use Device Manager, it can be very intimidating. Moreover, it does not always convey accurate information when it comes to resource conflicts like the one you may be experiencing.

May I suggest the System Information Tool?

sysinfo.exe or Programs-->Accessories-->System Tools-->System Information

From there, click on the Hardware folder, and check under Conflicts/Sharing and IRQs.  NB, however:  Starting with Windows 2000 and XP, Windows deals differently with IRQs. It alows several devices to share the same IRQ, typically IRQ 9. Contrary to popular belief, this is not a problem.  However this usually doesn't happen with comn ports.

Usually with Com ports, the problem is this:
Com1 is usually I/O Address: 3F8 Interrupt: IRQ4,
Com2 is usually I/O Address: 2F8 Interrupt: IRQ3

If either of these settings conflicts with any other device, you may be forced to adjust the settings for one of the devices (but not both.) Be forewaned that this can become difficult and stressful to fix if you are not familiar with it, and you can make the problem worse, in some cases. If you're not sure, consult a local expert.
