emulation on host: fix nasty delay (#5840)
emulation with socket: fix nasty delay properly check all return values (read() returning 0 indicates closed peer) ClientContext::state() triggers read() to check for closed peer uart emulation on tty: add cmdline -b debug option to disable raw tty hide annoying MOCK messages, add cmdline -v option to show them uart emulation on tty: check more return values emulation on host: tcp/udp port shifting: new cmdline -s(port Shift) option
