...embtclhandlers)5.1
Strictly speaking, flushing is not necessary in the embedding case to make the data available to the other side. However, it is needed in the remote case, and for compatibility and good practice, flushing is recommended.

... toec5.2
For compatibility with previous versions of the embedding Tcl interface, the mode can also be specified as r (equivalent to fromec) or w (equivalent to toec). These can be somewhat confusing as read/write status depends on from which side the queue is viewed (a read queue in ECLiPSe is a write queue in Tcl).

... e.g.5.3
It is possible to use the same name for both the queue stream itself and the event. This simplifies the event handler code because it receives that name as an argument.

... process6.1
The ECLiPSe side may be more complicated than a simple ECLiPSe, as it can be an embedded ECLiPSe, or the ECLiPSe process and other attached remote processes.

...remote_connect/3 6.2
Instead of remote_connect/3, the more flexible remote_connect_setup/3 and remote_connect_accept/6 pair of predicates can be used. See the reference manual entries for these predicates for more details.

... empty8.1
Note that this invocation occurs only if the ECLiPSe side of the queue is empty. If you have written data to the queue on the Java side, but not flushed it, the ECLiPSe side may still be empty, in which case the dataRequest method of the listener will be invoked.
