Nmap for windows nmap to identify an open port as being an RDP listener

Nmap for windows nmap to identify an open port as being an RDP listener

For example this is the IP range: 12.0.0.0-12.255.255.255 default port is 3389, i want to scan the entire Ip range with ALL open ports between: 1024 and 49151 So the final result must look like this,is just an example:

12.0.0.8:3389

12.0.255.220:3333

12.8.10.100:2008

12.12.200.18:4489

This is my code, it's just an attempt to scan,the code is incomplete:

nmap -Pn -p 1024-49151 12.0.0.0-12.255.255.255

thanks
