View source for 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 [[Serial_Pin-outs#RS-232_over_DE-9|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 [[Serial_Pin-outs#RS-232_over_8P8C_.28Sun.29|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 [[Serial_Pin-outs#Almost_Rollover_Cable|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 [[Serial_Pin-outs#Grey_DB-25_Female_to_8P8C_Adapter|nonstandard DB-25<->8P8C adapter]], to a [[Serial_Pin-outs#Dumbterm_Cable|special twisted pair cable]], to a [[Serial_Pin-outs#Black_DE-9_Female_to_8P8C_Adapter|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.
