How can I add four or more devices in my serial ports using IDE?
Serial ports don’t use IDE. Most motherboards nowadays come with either one or two hardware serial ports. You used to be able to get ones with four, but their popularity has waned in recent years. If you need more, you might be able to buy an adapter card (which will probably be ISA, so check before you do) Before USB gained popularity, it was common for internal cards such as modems to assign themselves “virtual” COM ports, which didn’t physically exist but were used as lines of communication Also, in case you’re referring to Serial ATA (The potential replacement for PATA, commonly just called IDE), most boards again come with just two adapters, for connecting two devices.
