As I see it, you have two options:<br />
1) buy an I/O card with 2 serial ports (about $15) check out I/O cards under this link: <a href="http://www.jdr.com/interact/categories.asp?cat=I/O+Cards/Drive+Controllers" rel="ugc">http://www.jdr.com/interact/categories.asp?cat=I/O+Cards/Drive+Controllers</a><br />
2) buy a USB to serial converter (about $60) <a href="http://www.jdr.com/interact/item.asp?itemno=USB-SER" rel="ugc">http://www.jdr.com/interact/item.asp?itemno=USB-SER</a><br />
<br />
But I wouldn't actually buy from this company - they tend to charge 25-100% more than others.

Could you use a simple switchbox ?. I used one for simple serial communication and it had 4 out-lines and 1 in-line. I don't the requirements of the devices you want to communicate with, so i can't say if it will work.

Software is any set of instructions that directs a computer to perform specific tasks or operations. Computer software consists of programs, libraries and related non-executable data (such as documentation). Computer software is non-tangible, contrasted with computer hardware, which is the physical component of computers. Software written in a machine language is known as "machine code". However, in practice, software is usually written in high-level programming languages than machine language. High-level languages are translated into machine language using a compiler or interpreter or a combination of the two.

Software

Hardware includes cell phones and other digital living devices, tablets, computers, servers, peripherals and components, printers and scanners, gaming consoles, networking hardware such as routers, hubs, switches and modems, storage devices and security equipment such as firewalls and other appliances.
