TCP/IP API Communications
The TCP.API.LISTEN initialization parameter enables an API to communicate with a IBM® Connect:Direct® using TCP/IP via OE sockets. Also, you can use the TCPAPI keyword parameter in the adjacent node record to define a default protocol for API communication.
The API must also use the SIGNON command to specify a transport type and communications address. See API Signons for more information. Additionally, refer to Managing Sessions in IBM Connect:Direct for z/OS® User Guide for more information about the SIGNON command.
