Serial Data Problem
Hey guys i'm using proteus 7.4 sp3 and its working fine until i do serial programming, i have connected a virtual terminal to see what the output would be etc... now sometimes when i make a new project and use my code it shows perfectly on the terminal but when i make...

but the following after passing through max232 shows something else
But if it's getting inverted then i wont see the desired output when i attach a serial cable and test the output in hyperterminal????
