Thanks, but that doesn't make it easy (of course) to create a Filter to read
the complete string. The closest I can get is to define an end of message
indicator (for my app) and look for that.
Since I test the app with telnet I don't want to be too fancy (i.e. embed
the length as the first X characters, etc).
