Hi aelfassi,
it's some years ago already when we had to connect a few different devices (mainly scales, scanners, modems, POS displays ..) through serial connections. In all of these cases it had been possible to make things working with WINDEV's set of commands. You have to know the basics of serial communication ... a library doesn't help much without that knowledge. Recommendation: connect the device to your computer and start to access it by using a test program. Btw: what type of device is it?

Hi,
no Need for some external stuff. We are using Serial communication since all the time in 24/7 applications.
Do not remember any Problems so far. What can a library do else than sending and receiving data from or to a buffer?
Super easy with WD. And initialization, too.
If you think about protocols, then you might use a library, but this should be generic (no Special hardside communication included).
Hope this helps

Hi,
probably you will need a library with most other programming languages indeed because Windows closes all ports - even parallel and serial ones! - by default. It's a security feature. Those libraries open the used serial port and do all the low level things you have got in WINDEV by default. Therefore you don't need a serial library in WINDEV.
