xterm launched using Xming doesn't repond to my keypress

I am using Xming for the first time after installation.

I launched the xterm window using the following commands

Xming -ac -multiwindow -clipboard

plink -ssh -X bi75630@devimbr1a xterm -d l6042762:0

When I try to type in the window it doesn't respond to my key press.

I have attached the screenshot.

Could someone help to figure out what might be the cause?

The Xming Release is: 6.9.0.31
