Manage RST signal

hello
I have Fastrack 1306b
How can I manage RTS signal? I need set RTS signal active or inactive.

Do you mean from an Open-AT application?

What version?

from open at application.
ver. 3.13.02

Please more suggestions! Problem is still exist.
Thanks!

I don’t think it is possible.

Perhaps if you could describe your actual requirement, people might be able to offer suggestions?

Modem send data via Serial port to second device and waiting response, if device is not send response then modem set RTS signal is active and device reboot

So could you use one of the GPIOs instead?

Where can I read about GPIO?

Thanks! I understand)
