TCP/IP Sockets Programming Guide

Communication throughout these networks has often been based on the Systems Network Architecture (SNA) family of protocols. XCICS TCP/IP offers XCICS users an alternative to SNA, the TCP/IP family of protocols for those users whose native communications protocol is TCP/IP.

Of course on Unix/Linux or Windows systems the socket APIs calls are the best way to interact with the TCP/IP protocol but, in order to support application coming from the mainframe as well as to make easier the life of COBOL and PL/I programmer, XCICS/TS supports the IBM EZASOKET API.

Applications running on XCICS/TS may communicate over TCP/IP with both direct socket APIs and EZASOKET APIS.
