Serial Connections
This article documents the physical serial ports on each machine and the connections between them. These connections are used for console access using Conserver.

Machine Ports
Most machines either have no serial ports, or one DE-9 serial port. Details of other configurations are listed here. We do not have any modems (DCE), so all connections should be crossed (i.e., use null modem cables or compatible).
taurine
taurine has a virtual serial port that can be accessed via telnet or SSH
ttyS0 physical DE-9 ttyS1 virtual
ascorbic-acid
ascorbic-acid has two Sun 8P8C serial ports stacked vertically, with the first port on top. The first port may be used to access LOM, and probably has to be set to 9600 baud.
A (ttyS0, LOM) B (ttyS1)
These ports should be connected to another system's DE-9 using a DE-9<->8P8C modular adapter and an Almost Rollover or standard rollover.
potassium-citrate
potassium-citrate has two DE-9 serial ports side by side, with the second port on the left
101102 (ttyS1) 101101 (ttyS0)
citric-acid
citric-acid has two DE-9 serial ports stacked vertically, with the second port on the bottom, and a dead DE-9 labeled "modem" to its right. The first port must be run at 9600 baud to access the embedded remote console.
ttyS0 ttyS1 modem
sodium-citrate
sodium-citrate has two DE-9 serial ports side by side, with the second port on the left
ttyS1 ttyS0
caramel-colour
caramel-colour has two DE-9 serial ports

dumbterm
dumbterm has one DB-25 serial port. It is currently connected to a black nonstandard DB-25<->8P8C adapter, to a special twisted pair cable, to a nonstandard 8P8C<->DE-9 adapter. All of these pieces are labeled "dumbterm". The dumbterm cable is not symmetric; the end labeled "DE-9" must be plugged into the DE-9 adapter.
