Phinx does not accept keystrokes, from windows

I am using Phinx for running remote desktop over X.
I can see the login QNX screen on Windows. however Phinx is not accepting my keystrokes. The CTRL keys work in a xterm (within Phx).

I’m using Xming, PuTTY to connect to remote QNX machine,

phrelay is uncommented in inetd.conf, inetd is running. I see three phrelay -x running for each Phinx.

Please help
