The USB to serial converter is widely used for connecting with devices such as digital camera, modem, ISDN-TA modem, barcode reader, Palm III and V, tablet, label writer, fingerprint verification, security system, POS equipment or any of other serial devices.

Important Note:
1. The 9 pin and 25 pin ports don't work at the same time, which means only one serial port (DB9 or DB25) is connected to your computer at a time.

2.The adapter is with lugs, so if your modem's port also have the lugs, you might need a spacer. Please do careful if you insist on trying to remove the lugs, and it's not recommended because the adapter could be mangled likely.
