The one's I've used are Seyon (X Gui application) and screen. Either will do.
The more interesting part is hooking up the serial cable, which is particularly interesting on the Pi Zero, since it doesn't have GPIO pins to connect to - it just has "holes". So, to connect to the GPIO, you either have to solder in a header block (so that you get pins like in the other Pi models) or you have to jury rig something to connect the wires to the holes.
