More about the COM port number: 
In Windows right click My Computer, select Properties, then Device Manager. Open up the subdirectory list for Ports (COM & LPT) and Universal Serial Bus controllers so you can see what happens when you plug and unplug the USB-RS232 converter. Notice that "USB to Serial Converter" is added to the list when you plug it in and removed when you unplug it. Notice under "Ports" a new entry named "Serial On USB Port (COM nnn)" is added when you plug in the cable and removed when unplugged. 
You can change the COM port number assigned and it is remembered by the converter. Double click on "Serial On USB Port ...", select Port Settings, then Advanced. Notice you can specify the COM port number that will be used, from 1 to 256. Notice that you can remove the cable and install it later, in any USB port or connected HUB, and it will still be the same COM port number. 
Requirements:
Pentium-class PC with USB port, Windows 98SE, ME, 2000, XP. (Not W95 or early versions of 98). 
DOS programs don't work, nor do applications that bypass the Windows API and go directly to the hardware. 

Specification:
FCC approved for home or office use. Full RS-232 voltage levels +/- 10VDC, on all signals, TD, RD, DTR, RTS, CTS, and DSR. Operates up to 115k baud. 
Driver software included on 3.5" floppy. You can download the latest drivers for MAC and Windows… choose "USB-Serial Converter" for PC or Mac. Known Problems. 
System problems - Some laptops appear to work when on AC but not on batteries. This is because XP is powering down USB devices. This can be controlled in the device manager. 
Application software – typically the application software must have been written or updated after Windows 98 came out and it must be calling the Windows 32bit virtual COM port driver correctly. DOS based software will not work, nor will many programs written prior to the existence of USB (first supported in Win98 and not well supported until Win98 SE (Second Edition)).
