/*============================= writing related code ===========================
|
|
|
|
|
The logic here is to use the standard writeHandle when available. I expect most
|
|
|
|
|
communication to be short and to happen through the writeHandle. If that one is
|
|
|
|
|
in use, a new connection will be built.
|
|
|
|
|
---------------------------------------------------------------------------------
|
|
|
|
|
suppress all superfluous OK from the slave
|
|
|
|
|
This works by sending the command via contextdo with a ID > 10^6. This causes
|
|
|
|
|
the remote SICS to send the termination messages. The transaction IDs together
|
|
|
|
|
with the connection responsible for it are kept in a list.
|
|
|
|
|
|
|
|
|
|
This list is used by the write task to forward messages properly and for handling
|
|
|
|
|
termination.
