    Could anyone be so kind to help me out? The only solution for me was a 300 baud rate, but it takes 2-3 times more time to finish something because the code is loading too slow and the machine is waiting for it to load every so often.

    I've tried setting xon/xoff and it has worked for me before but for some reason, when i changed the laptop that loads to the machine, it's not working properly. I've also tried with other setting but no luck. When I set the baud rate to 2400 for example, The program loads only 10% of the machine memory and then it states "Input overflow", and stops every action.

    I had to change the laptops because the old one died.

    ...USB to Serial adapters are sometimes the problem if, that is what you are using.
