Shut down your computer, turn off the power, and restart it.
Going through this power cycle can be important.
Merely restarting Windows may not allow the BIOS to reg-
ister the changes properly.
If Windows finds your other serial port, it may try to assign the
port to COM2, but won’t be able to because your Modem is al-
ready using that system resource.

Solution
Your PCI Modem is a BIOS and driver-dependent device. Some-
times the modem will be mistakenly assigned to an IRQ (Interrupt
Request) already in use by another device.
If you install the modem in a different slot in your computer
, this
may solve the problem.
You should also check your computer for an available IRQ if you
have other devices connected to your computer.

All Windows operating systems:
When PCI bus IRQ steering
is enabled, Windows will direct PCI bus IRQs to devices such as
your modem. Sometimes, however, the IRQ that Windows as-
signs to your modem will conflict with the computer’s BIOS.
