This article documents the physical serial ports on each machine and the connections between them. These connections are used for console access using Conserver.
Local machine | Local TTY | Remote machine | Remote TTY | Baud rate -------------------+------------+---------------------+------------+---------- corn-syrup ttyS1 LOM <- corn-syrup-ipmi - 57600 mirror ttyS1 LOM <- sodium-benzoate-ipmi - 57600 taurine ttyS1 LOM <- taurine-ilo - 115200 glomag ttyS0 LOM <- glomag-ipmi - 115200 goto80 ttyS0 <- corn-syrup N/A 115200 goto80 ttyS1 <- corn-syrup N/A 115200 goto80 power <- corn-syrup N/A 115200 potassium-citrate ttyS0 <- corn-syrup:ttyUSB2 hub3 115200 aspartame ttyS0 <- corn-syrup:ttyUSB4 hub5 115200 electrons - <- corn-syrup hub8 9600
The "hubN" ports are on the 8-port serial hub. To access, look in /dev/csc, or just use ttyUSB[N-1] directly.
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 has a virtual serial port that can be accessed via telnet or SSH
ttyS0 physical DE-9 ttyS1 virtual
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 has two DE-9 serial ports side by side, with the second port on the left
101102 (ttyS1) 101101 (ttyS0)
sodium-citrate has two DE-9 serial ports side by side, with the second port on the left
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.
