Reverse GTEA / DSAD
A client TPR running under TP8 can communicate
with a server application on the open side using
the ACI8 APIs.

GTEA ( TCP/IP network )
GTEA
DSAD listens for request to connect to an
application on the open side, and then starts the
configured application. From that point the
application can use the GTEA APIs to communicate
with the TP8 Application.
