how to write code for displaying LM35 output on pc

HI,

I am using the following circuit diagram for recording the temperature interfaced with pc via serial port. But i dont know how to write code for that for displaying the digital output on pc periodically??? I using C#/C++/java for coding.
Any kind of help will be appreciated.

How is it interfaced to the PC? Have you a max232 chip to level change, as the voltage levels on the rs232 output on a PC are +15 / -15. You wll also need a driver and utilize the CTS, RTS, DSR or DTR lines.

i have not interfaced yet it with pc. will i need max232, if so then what will be the changes in circuit?

hi Ian
Its OK to link pins 1, 6 & 7 , also link pins 4 and 8 on the 9Way RS232 cable connector at the PC end, this will not require the control lines to be used/connected.

I expect the PC program to use the ON_Comm Event when data is sent from the PIC to PC.
