Ok, I'm not much of a programmer at all. I taught myself to write scripts that are compiled by the Open Watcom C++ compiler. I'd like to know an easy way to send to a serial port, USB or RS-232, either will be fine, the goal is to send some commands to some hardware. I can google and find tutorials on coding for serial ports in C++ but really, I'm hoping I can find something that is more "plug and play". I don't really have a clue what is needed, maybe a dll exists and I can call it from my script? I've always wanted an excuse to get PowerBasic, maybe I have to produce the dll? Maybe there is some code I can copy-paste into my script and compile it??
