i know about the 8051 programmeres........Actually i don't want to program it.....say for example i want to send a text file over serial link from pc to 8051......Is there any utility for this propose.......file should be transfered only after some trigger is applied..
I assume that you know how to communicate between the PC and the 8051? If yes then the easy way to do what you want is to create a packet of data. This can be very simple... choose 2 values that will never be in your text file. Make one the start character and one the end character. eg. ~this is text# Now when your program finds the ~ it knows that the next byte is the start of text and the # is the end. You could make it more fool proof by adding a length of data field and a simple check sum.
