Do you wait for the message to be sent to the server?

So effectively you would like the TCP sampler to support write-only
and read-only modes?
But in each case, the sampler would wait for the write (or read) to complete?
That should not be too hard to implement.
Though I think you would find it easier to write your own TCP
writer/reader that handled all the heartbeats.
