Enter the command in the command window of cmd: start / min telnet 192.168.3.42 8080

After that, a window will appear, which is minimized. Wait a minute. If the window closes automatically, the port is closed or the host ping is disabled, otherwise the port is open.

Netstat-anp tcp80 can view the current host tcp80 port.
