Solution 1009357.1 : Sun Fire[TM] 12K/15K/E20K/E25K servers: System Controller serial port configuration

Applies to:

Sun Fire 12K Server - Version All Versions and later
Sun Fire 15K Server - Version All Versions and later
Sun Fire E20K Server - Version All Versions and later
Sun Fire E25K Server - Version All Versions and later
Sun SPARC Sun OS

Goal

The serial port located on the System Controller for the 12K/15K/E20K/E25K servers can be connected to any other serial device, if the correct pin-out is used.
Below, are the pins and signals for the serial port.

Fix

Use the following diagram when creating a connection:

8 pins Mini DIN
------------------
Signal, pin number                    -----------
------------------                   /           \
DTR        1                        /  8   7   6  \
CTS        2                       |               |
TXD        3                       |  3   4     5  |
GND        4                       |               |
RXD        5                        \    1   2    /
RTS        6                         \           /
DCD        7                          -----------
NC         8
------------------

Examples:

3 wire serial null modem cable.
Use x-on,x-off (software handshaking)
