are you trying to say that the port recognizes the ttl logic levels from the uC? Absolutely not! Erik is saying that some people think they can get away without an RS232 transceiver. They try it, and they're lucky - it just happens to work with their particular setup. What they don't realise is that it is working only by luck; it only needs something to change - like a new PC or new motherboard - and everything could easily just stop working. |
