INT1 and Host Connections

The following table shows how configuration parameters and other circumstances determine which host application you access using INT1.

If you selected Auto-Connect in the path configuration, the specified host application opens automatically when a terminal emulation or file transfer session that uses that path is opened.

If you cleared Auto-Connect, the host application opens when you press the transmit key or issue a $$OPEN command.

Command Issued from Terminal Emulation	Environment for the Path	Result
None	A configured environment	The host application associated with that environment opens.
A $$OPEN command that matches an environment name	Does not apply	The host application associated with that environment opens.
A $$OPEN command that does not match an environment	Does not apply	The specified host application opens, using the connection specified for the DEFAULT environment. If no DEFAULT environment exists, you receive a message indicating that terminal access is restricted. To avoid this message, create an environment named DEFAULT.
