the usb adapter is the tricky one, as is your laptop
drivers usually need installing for a start , plus it all depends on the windows operating system being used as well
the cheaper oem versions of 7 , 8 or 10 may not work , maybe not vista home either
the ideal is an old xp pro desktop, tower or laptop that has a 9 pin com port fitted, I have at least one of each myself and so never use anything else
win 7 pro or ultimate should work, win 8.1 pro should work , win 10 full or pro version should work
the usb adapter and the windows os are your weak links and prone to failure
some of those usb adapters never work, yet will operate a serial mouse or a modem
