How do i enter into suspent mode in USB-to-UART converter?

I have this converter:
https://www.sparkfun.com/datasheets/IC/cp2102.pdf
It is said there that:
"The CP2102 will enter Suspend mode when Suspend signaling is detected on the bus"

What does it mean "Suspend signaling"?

If i keep the Suspend_NOT pin connected to ground (through pull-down), will it keep me on suspent state?

Thanks.

I have no experience with this chip, but according to the datasheet, those suspend pins are both outputs and signal when the chip has gone into suspend mode. One goes high, one goes low. I'm guessing 'suspend' is a signal that's sent over the USB bus.

Trying to input anything into those pins isn't going to get you anywhere. It mentions that you can tie the 'low' pin down with a strong pulldown so it doesn't float at startup, but that's it.

Suspned is a particular series of states on the USB bus. You can download the usb specification at USB.org - Welcome

From the file USB_20.pdf go to section 7.1.7.6 for a description of suspend signaling.
