Shell over serial with DCSD & jailbroken device

zsh is broken on my device, too lazy to fix, waiting for 9.3.x jailbreak.
I used qwertyoruiop's serialsh tool, which is on my repo cuz it was a pain to find it.
DCSD cable needed. You can buy one on vipprogrammer, can take a while to be delivered.

my repo is full of crap i don't know what is working or not.
