The USB port is hardware.
A COM port can not be converted to a USB port just by using software. The signal types, levels, protocol, connector type all are different.
A serial port can be connected to numerous devices; pretty much any device that has another serial port. Examples include: Modems, serial mice, serial printers, bar code readers, digital scales, data acquisition equipment, pumps, flow monitors, radios, etc. I have a ham radio receiver that is controlled completely through a serial port and custom software; and I am writing a custom piece of software right now that connects through the serial port to a digital scale for process automation.
No, it does not come with software.

A port is a software address on a computer on the network--for instance, the News server is a piece of software that is normally addressed through port 119, the POP server through port 110, the SMTP server through port 25, and so on. A socket is a communication path to a port. When you want your program to communicate over the network, you have given it a way of addressing the port and this is done by creating a socket and attaching it to the port. Basically, socket = IP + ports Sockets provide access to the port+ip
You can check and see like what or you could go to control pannel and then add or remove hardware and check and look at the stuff that's downloaded on your computer. Answer 2: This is caused by "some software" on your computer opening (or mapping) that particular port for communications, or the firewall preventing the opening of that port (software does not always know why it cannot map that port). You would need to find the software that is blocking that port and shut it down, or open the port in the firewall. There is software available that explores what open ports you have, and what it is mapped to. Rather than recommend one over another please search for "port Explorer" at you favorite download or search site. Select the best software for your requirements, and use it to find what is killing that port. Please remember that opening a firewall block on a port could lead to security problems so take caution in your actions.
The default FTP port is 21. But most FTP server software allows you to set which ever port you want.
