Ok, I see...
I don't really understand why you wish to async_read() char-by-char and to
re-run io_service each time, instead of reading N chars at once into a
buffer, but if you prefer to do so, you have to call io_service::reset()
before any subsequent call to run():
//...
io.reset();

io.run();
//....
