hey guys i was trying to simulate serial programming on proteus and tried to send a character, i added a virtual terminal at the beginning before passing through max232 and i could see the character fine... but after passing through the max232 i never got the same character again... like if sent 'A' i would get '_' after passing through max232.... can anyone please help :S
the vterm in ISIS has to be inverted to connect a mx232 in simulation... have you selected to invert RXD and TXD in the vterm properties??? maybe that's the problem...
I know this very old thread, but I want to put the answer there just incase anyone look for it.
Right click on the virtual terminal, edit properties, change from normal to inverts.
