AFAIK read_some() should only block if there is no data to read at
all. You could check for that with:
std::size_t bytes_readable = command.get();
Or you implement your own read() function with async_read() and
deadline_timer, like here:
-- echo mailto: NOSPAM !#$.'<*>'|sed 's. ..'|tr "<*> !#:2" org_at_fr33z3
