    Hi Rick. Colour changing being an elegant idea of today (after protocoll finished). Back in my monocrome days split screen was the saviour. 73. Finn/LA7UM

That number counts down with each ACKed transmitted frame in ARQ mode (or with each from sent in FEC mode) . When you add more text from the keyboard text box it increments back up. The value shown is always the data still pending to be sent.

Its “just a small matter of programming” to for example change the blue italic text in the Session window to something like purple italic or something AS each block that is queued is ACKed. Actually it is not trivial coding but it can be done. But FAR MORE important than this however are more difficult tasks like:
