hack-y state machine to indicate when we've seen the special string 'DONE!!!' from the pi telling us to shutdown.

eat the rest of the line up to a newline.

uses select to see if - stdin (file descriptor 0) has input - the pi fd has ouput.

read and echo the characters from the usbtty until it closes (pi rebooted) or we see a string indicating a clean shutdown.

We wait until no characters for 1ms. Otherwise I think we can sometimes get random stuff from previous connections. This is still a race condition (

this is our attempt to do a hard reset so that you don't have to pull the esp in and out your computer. NOTE: this is *NOT* guaranteed. i experminte

we get 4 digits of precision.

read the entire line into <buf> and null terminate it. returns 0 if it was empty.

we have a limited view of spaces: otherwise will wander onto the next line.

you want to get a response, and then get an ok --- the way the code is setup now, you can bail if you just get an ok without filling anything in. is
