Arduino Auto-RESET Query

Development Tools IDE 1.x

Hello, I have an USB to UART IC that has only RTS pin, apart from the usual VCC,GND,TX,RX,USB_TX and USB_RX. Now, I know that Arduino uses the DTR signal to reset when connected, or opening the Serial Monitor, or during program upload.
Now, can I use the RTS pin for the same job? Or do I have to think of an IC with RTS pin altogether?

Please also mention about Operating System compatibilities, if you know (I mean, will the RTS signal work for Windows, Mac and Linux ?) .

Would prefer if someone reply me on my topic, rather than suggesting alternative ICs. I am well aware of other ICs out there, but I am just fascinated to know if this works or not.

DTR and RTS acts jointly, driven by SW on PC side. It doesn't matter which one is used.

Thanks. Yes it is working...just checked. Logic level on timing diagram is exactly similar. :slight_smile:
