2. To receive technical information with GPS device port 5055.

How to open a second port?

Answer 1

In a hosted Cloud9 workspace, you can listen on ports 8080, 8081, and 8082. Only these three are mapped externally. Port 8080 is mapped externally to to http://<workspacename>-<username>.c9.io while 8081 and 8082 need a port specifier e.g. http://<workspacename>-<username>.c9.io:8081
