arduino and visual basic serial communication

hi, i have figured out how to send serial data from arduino to visual basic and the other way, but for some reason when this happens fast after each other, it starts doing crazy things.

What is the best way to get serial from arduino to visual basic and the other way as fast as possible ?

I want to use it to read and set variables on my arduino

"it" is a pronoun with no referent. WHAT starts doing crazy things?

Make sure that neither end has any blocking code.

Permission granted.

Now, where IS your code? You were SUPPOSED to post it - all of it and in code tags. Read the stickies at the top of the forum that you were supposed ot read before you blundered in here.

You can use the examples in serial input basics to receive data on the Arduino.

The same general approach will also work in other languages on other computers
