@Mammmood - I don’t think that I’ve seen rollover cables. However, I have used null modem cables at work. I work in the utilities industry, and often have to connect my relay test set equipment to my computer to do testing. The computer only has a USB hub, but the test set has a serial port.
So I use a null modem cable to connect the serial port on the test set; one side of the cable has a serial adapter and the other has a USB connector. It works perfectly.
