To communicate with STK using Connect commands from an external
application or an HTML page, you can use:
A TCP/IP connection to send Connect commands over a
specified port. The default port for this connection is 5001, but
you can change it by selecting Edit->Preferences
and choose the Connect page.
The COM interface to STK (see the Integration Help
System) to send Connect commands directly to STK without
communicating through a port.
Note: Sending asynchronous connect commands
to STK is not supported over COM.
