Compatible with Windows® 7! Connecting USB with the traditional RS-232 serial port, this adapter connects cellphones, PDAs, digital cameras, modems, or ISDN terminal adapters through your USB port. Has a data transfer rate of over 230 kbps. Since the adapter uses no IRQs, there are no IRQ conflicts, and it is ideal for when you need many serial devices attached to your PC.
