    Seems these days if you want your software to talk to the outside world, all you have to work with is the virual USB<->Serial and USB<->Parallel devices. Especially in laptops. Someone in their wisdom thought that these devices are a suitable replacement for "real" ports. (ie UARTS and parallel i/o chips). You have to rely on the bulky overhead and often buggy device divers. In reality they lack performace and versatility. Bring back the serial port. Anyone with me! :)

        In contrary to a handful of hardware registers in a UART or PIO. I could write drivers for them while sleeping (and wake up in the morning, looking for the elves who did this).

        As anybody who wanted a faster floppy drive on a C64 or Atari 400/800 would have been able to tell us. Why should the hardware guys stop making the same mistakes all over again when the software guys also keep bringing back yesterday's mistakes? :-)

        The language is JavaScript. that of Mordor, which I will not utter here
        This is Javascript. If you put big wheels and a racing stripe on a golf cart, it's still a fucking golf cart.

            Never thought of that as I do not work with the hardware that much any more. Once wrote a program using the RS232 port to take data. And since they did not need as many people to run the tests, they fired me. :)

              9 pin D-type all the way! Also a proper parrelle port, with those two I could control the planet....

                  I have programmed RS-232 serial and parallel ports since the DOS 3.3 days (remember hooking the UART interrupts in DOS?). Frankly, with all the embedded systems I have worked with in the last 25 years, I can't say as though I miss having a dedicated serial or parallel port on my PCs or laptops. I have had only 1 case where the RS-232 cable driver was buggy and caused problems for my system, but using an older version of the same driver ended up working just fine. If you get a USB-RS232 cable, most of them use either the Prolific or FTDI driver. It is a better idea to go to Prolific's/FTDI's website and get the driver from there. The ones that come on the CDs provided with the cables generally are old and not very good. So for me, no.

                    1 USB port = about 2.4 micrograms. 1 parallel printer port = about a kilo and a half. Which do you want on your tablet?

                      100% Agree. I work in Machine Automation, and we constantly have to work with factory-grade devices like printers and servos and even robots that still use serial communications, and you have to buy two or three of those darn USB<->Serial adapters before you find one that works.

                        Well.... yes n' no. The serial port was a nice static "come sit stay port" but had it's issues. DB9, DB25, baud stop bits large size etc. The USB port solves the serial port's issues but alas, has it's own. I have been around since pdp-11s were crank started. Put a gun to my head and I choose....... USB.

                          Yah, but imagine the cost you will have to pay as only 0.01% of the population wants those anymore... they will have to custom design your whole system for that, and it wont be one of those tiny light as a feather, thin as paper laptops ;P
