TCP/IP connection with SAP PO

Hi experts

In my project ealier the intergration of 3rd party(receiver system) was done with Jco

JCO was sending some bits(data) over the TCP/IP connection to the 3rd party

Now the JCO is being replaced by  Pi as a middle ware.

But the problem is that  receiver system can only have.understand TCP/IP connection

does anybody has any idea, how we can do it with sap pi.

Thanks
