VTCPD

The VTCPD (VPS Transmission Control Protocol Daemon) process is usually

executed from the ase.cfg file (see The ase.cfg File on page 148) during system

startup (as opposed to being started from a command line). It provides a general way

for applications to communicate with one or more external hosts through TCP/IP

connections. To voice applications, the daemon functions as a resource. To perform

host interaction, applications use the standard functions for acquiring, freeing,

sending, and receiving resources.

The VTCPD resource is very flexible and can accommodate a wide variety of

application requirements and host configurations. Included in these configurations

are:

• connection to multiple VMST processes,

• one or more connections to a single host,

• multiple connections to multiple hosts,

• connections to yet-to-be-specified hosts and port numbers,

• one connection per line and running multiple VTCPD daemons with one or

more hosts.

If VTCPD is set up for multi-host interaction, in the event of host communications

failure, it can be configured to automatically switch to another host.

This section documents only the configuration of the VTCPD daemon process. For

information about application communication with TCP/IP hosts, refer to the VTCPD

Feature Description Manual.
