Serial Pin-outs

The idea is to connect pairs of systems with 2 serial cables to create a bidirectional link. We would then run a getty over one of the ports on each machine. This would allow us to login to any server if networking breaks.

The following is a list of our servers and how many serial ports they currently have:

• caffeine (1 or 2)
• natural-flavours (1)
• artificial-flavours (1)
• perpugilliam (2)
• citric-acid (2)
• potassium-citrate (2)

Phosphoric-acid and caramel-colour have serial port brackets that connect to motherboard headers. We can likely use them to add an additional serial port to artificial-flavours and natural-flavours.
