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

ttyS0 on motherboard I/O shield
ttyS1 on motherboard in a PCI header

phosphoric-acid

phosphoric-acid has two DE-9 serial ports

ttyS0 on motherboard I/O shield
ttyS1 on motherboard in a PCI header

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.
