@notty hostname when using terminal

When using PuTTY, it shows different same as the hostname I set, but when login to WinSCP and click on Terminal, when I type ps x it shows username@notty. How do I set it to follow my setting on server or is there customize the hostname name?

WinSCP Console window does not implement terminal emulation => notty.
If you need full terminal, please use Open in PuTTY command.
