I have compiled the UDP/IP demo. I have the debugger running the command line. And it obtains an IP address on my Windows PC. When I try to use the YAT it displays a messege:

Unable to start terminal! System error messege: Only one usage of each socket address (protocol/network address/port) is normally permitted.

YAT hint: Make sure the selected socket is not already in use.

How can I go about checking if this network address/port is in use already ?

I think this is more of a Windows question that a FreeRTOS question...
