When would you disable the serial port?
In the past, both the serial and parallel port were the most common means of data transfer and communication used by PCs. Serial ports were used for devices such as modems, mice, and serial port printers. However, in newer PCs, both the serial and parallel ports have been replaced by the use of USB ports. You should only disable serial port(s) if you are absolutely certain that auxiliary devices such as modems; printers; mice; etc.. are USB based and that your PC has enough USB ports to accommodate all of your auxiliary devices. Note: If at some point in the immediate future, you plan to sell your PC, it might be wise to leave the serial port as is.
