"Yes" - see the bool term member of the RemoteTransport class.

Does it work properly? - No, because the change to the regular bool
member might not reach the other execution thread due to caching etc CPU
effects. Sword++ switched to std::atomic<bool> to fix this case:

There is a similar issue regarding aborting of indexing.

Network issues (connections hanging etc) is how we first discovered this
issue with BibleTime long time ago. The user gets stuck in the download
dialog and had no means even to navigate away from it. The only possible
way is to kill the offending BibleTime process.

As far as I know it is currently not possible to configure a timeout, so
it might just hang indefinitely. ;-(
