This chapter contains sample programs using NetIPC for both TCP access and
X.25 (level 3) access:
- Example 1 (programs 1A and 1B) present an example of how to set up and
use a connection (virtual circuit) for TCP access. The two programs,
running on different nodes, open communication via call sockets. They
then establish a connection (using VC sockets) and send and receive data
over this connection. Finally, they terminate their connection.
- Example 2 (programs 2A and 2B) illustrate the differences in using
NetIPC for vectored I/O in compatibility mode and in native mode for TCP
access.
- Example 3 (programs 3A and 3B) provides an example using NetIPC to
communicate using direct access to level 3, X.25 in compatibility
mode.
- Example 4 (programs 4A and 4B) provides an example using NetIPC to
communicate using direct access to level 3, X.25 in native mode. These
programs use the features provided with MPE XL X.25 such as adding to
the facility field, and using fast select.
In these programs, it is assumed that processes are already operating at the
remote and local nodes. For an example program that illustrates the use of
Remote Process Management (RPM) intrinsics to start processes, refer to the
Using NS 3000/XL Network Services Manual.

NOTE:
You may need to disable timeouts on either the call descriptors or virtual
circuit descriptors when writing applications intended for use on networks
where you expect significant timing delays due to excessive line noise or
traffic.
