WiseMo modules as default use port 1970. You can define the target computers should listen on a port of your own choice, by configuring the TCP/IP communication profile found in the Host module.
When calling a Host module from an Android Guest or an iOS Guest (iPhone, iPad) you will usually just enter the IP address of the Host computer. If the Host is setup to listen to a non-default port, you can add this port number to the IP address, before connecting to the Host computer. <ip adr>:<port number>
Example: In the Host ID field, you enter: 10.240.1.3:1975
This will call using port 1975
(You can do the same from the Windows Guest, but here you can also define the port number in the TCP/IP communication profile).
