Old Comm Software w/ only COM1 or COM2 ouput - need to connect via USB modem

The interface from my PC to my telephone switch uses a dos program that allows only COM1 or COM2 selection.  My new motherboard does not have serial output and I'd prefer not to install a serial PCI card.   How can I redirect the output of my comm program to my USB modem ?

if com 1 is assigned it needs changing first

Change the COM Port Number
To change the COM port number:
1. Click Start, point to Settings, click Control Panel, and then double-click System.
2. On the Hardware tab, click Device Manager.
3. Double-click Ports (COM & LPT).
4. Double-click the appropriate COM port.
5. On the Port Settings tab, click Advanced.
6. In the COM Port Number box, click the appropriate number
 
7. Click OK.

Bradleys40 -

I'm afraid I can't see how your solution would work.  The problem is the solftware.  What kind of adapter would attach to a program that outputs only to COM1 or COM2 ?  A USB to Serial adapter assumes that I can already get the output of the software to the USB port.  I can't - there is no physical COM port.   Are you saying that there's a device that plugs into a USB port and picks up COM output from my software?   Sample part-number ?

I have used a usb to serial adaptor for connecting via com2 to a network switch using an rs232 serial interface.
the software with the adapter it creates a com port, you can change the com poort numbers
the application the uses the com port will be directed through the usb adpter to the serial interface,
therefore you will have a serial interface available to plg in whatever you need.

I hope this clarifies things

there are loads on amazon
all you need to do is connect your serial modem after you have followed the steps
see below link for adapters

Works fine - couldn't see at first how the software's COM output would translate through the USB port, but the drive that came with the adapter apparently took care of it.  Thanks
