Unable to launch TCP protocol in SoapUI Pro

Dear Team,

Our product/webservice is launched as a TCP protocol and we have no idea of where to start and how to begin with a TCP request. Requesting Technical support on this please. 

For now, we are trying to check if soapUI pro could support TCP. If it does, then we would buy a licensed version of it. IT all depends on how well we are able to make it useful for our protocol. Thank you
