For my project it must be possible to check different bytes from \x00 to \xFF via tcp-check expect rstring. But it is not possible to check NULL bytes. Everything after the first NULL byte will be ignored. My test configuration: tcp-check send-binary 9C00000800870100 tcp-check expect rstring ^\x9a\x00\x00.{5}\x00{13}\x10\x00\x04
