Many people think it's only 2 wires (TX / RX) comunication. Well you are deadly wrong, you can see in http://en.wikipedia.org/wiki/Serial_port have a lot of other signal and the problem is many "serial usb" conversor are not working properly. I'm having nightmare trying to conect some "not so old" devices with serial port through this "serial-usb" conversor, many simple don't work.
The true is the comunication with serial port is a mess. You don't know if you are receiving or transmiting correctly unless you "alredy" know what you will receive and can check the integrety by youself or the data your sending to device is correct. You even don't know if there are anything conected in serial port. Bottom line, there is no standard for reliable comunication.
Yes, It's easy to develop to serial, very cheap to construct devices with serial port and (for embedded) is very low power consumption, but I think is time to let go this type of device.
I don't understand why all this concern about privacy "on public places". If you have a problem, why don't you wear a paper-bag?
It must be Saul Goodman XD
Probably they will ban "Clue", "Monopoly" and others "dangerous" games.
