You can support it by donation at your choice by button. You will need (like you mentioned) do detect whether either device (scale or printer) is attached to a comport, my gut feeling is that the scale is easy, but the printer might pose a problem. So enumerate the comports (TComport can do this) and start with the highest port going down. ![]() USB to serial convertors almost always get a 'high' comport number allocated (>4). I've tackled this problem by detection a couple of times before. ![]() I would have to spend a lot of time to get that acquainted with USB!!! I can understand a serial port down to the register level inside the chip. Other serial port systems such as USB are very complicated in their operation and extremely fragile in an industrial environment. ![]() Actually, standard serial comports are still being used by vast quantities of newly manufactured items such as weighing machines, bar code scanners, modems, satellite boxes, GPS, test equipment, medical systems, scientific instruments etc. ![]()
