It will prevent ACP from connecting to your scope. It will give no error message and try indefinitely
Thanks for passing that "trap" along!!

The "infinite delay" is coming from the driver for your mount. ACP will wait forever after setting the Connected property of the driver to True. The driver must "Do it right or raise an error" - the cardinal rule for drivers. If the call never returns and never raises an error, ACP will indeed wait forever. This is by design - "How long should it wait? And for which mounts?"
