TCP adapters

Enable a production to manage an incoming or outgoing TCP connection. The adapters allow simultaneous handling of multiple connections. They support character and binary data streams, and counted data blocks.

See Using TCP Adapters in Productions.

The TCP adapters are also built into many specialized production classes.

Availability: All interoperability-enabled namespaces.


The special variable $SYSTEM is bound to the %SYSTEM package. This means that instead of ##class(%SYSTEM.class).method(), you can use $SYSTEM.class.method().
