Abstract

A method is described which allows many communication applications that use SELECT to be ported to run on SNA networks with Advanced Program to Program Communications (APPC) extended for explicit multi-session support. Some UNIX* applications are written to send and receive data over communications networks. These programs for the most part use the UNIX standard I/O interface (i.e., open, close, read, write, ioctl). The APPC feature of the IBM RTPC workstation provides a standard I/O interface as well as the verb interface specified in the LU6.2 Architecture. Many TCP/IP applications use the SELECT system call in addition to the standard I/O interface.
