I need to send strings messages to an LCD through DB9 connection I want to use ISR interrupt vector to receive data from a computer, I will use an Atmega8 to control that. How can I perform that

Note: I have already developped and tested lcd library

Thank you

Since you say DB9 I guess you mean RS232 data transfer method. I am not quite sure what you want to do. But could it be that you want to send strings from the PC to Atmega8 controller, that in turn transfer the latter string to the LCD. On the Atmega8 controller you want the make an ISR that take care of the data from the PC.
I do not know the Atmega8 controller. But this is a very typical micro controller task. That should be quite doable.
