Many of the newer computers do not have serial ports as the use of them has nearly disappeared. If the need for a serial port is mandatory, try a USB to serial adapter. http://www.tigerdirect.com/applications/SearchTool
Just bear in mind that not all devices can use that adapter. The only way to know is to try it. If there happens to be a brick & mortar store near you to look and try a similar device, even better.
