BSD Sockets

The Trakker Antares terminals support a subset of the BSD (Berkeley Software

These socket functions are supported in the Trakker Antares Programmer's Software

For more information about these socket functions and using the PSK to create
programs, see the Trakker Antares Application Development Tools System Manual
