Hi,

If I'm using the software RS232. What is the best way to ensure that there will be no lose of characters in the receive side?
I can't wait for incoming characters all the time?!

If you have a free output, you could use that as a hardware handshake line for the transmitter.

You can poll kbhit() to see if data is arriving. You should poll at at least 5X each incoming bit so you only miss 1/5 of the start bit. You can poll less often but communication reliability may start to suffer.
