How to choose the best serial ports card

There are some things you should consider when buying a serial ports card. We spent 22 hours researching the most important things you should consider when buying a serial ports card. So should we start with the list of things you should consider?

Make a list of the things you want in your serial ports card and the price you are willing to pay for it.
