Serial Port Peripheral Problems

Hi Everyone,
So I know this will take you all back, but I want to configure a computer with two different serial port peripherals. The computer itself only has 1 port so I bought a PCI 2 serial port card and installed the software. In windows xp sp3 it sees the ports under the device manager, but when I run the appropriate program and scan addresses for the peripheral, it doesn't find it even when I let it scan the first 100 addresses. Is this normal? Is there a way I can specify the address number within windows or is something else going on?
Thanks!

EDIT-
Okay this is slightly embarrassing, but I actually just figured it out. It turns out that there is a difference between the port number and the address within the port. You should be able to set the COM port number within a given program and then just have it search for the correct address to use.
 
Newer programs can deal with virtualized port addresses (say COM1: which can be actually any physical port address/IRQ pair, COM2: etc.) Older programs may need to be configured with the actual port/IRQ addresses (like 2F8 IRQ 3, etc.).
