console mirroring allows a user on one serial port to monitor the service processor activities on another serial port. this can be done on the locally attached hmc virtual terminal window or windows remotely attached through modems. console mirroring is supported on any combination of locally or remotely attached monitors.

    the serial port from which console mirroring is enabled is called the primary port. the mirror port is determined when keyboard input is detected from one of the other two serial ports. from this point forward, the service processor sends information to the active port and the mirror port only. console mirroring ends when the service processor releases control of the serial ports to the system firmware.

    console mirroring is supported on serial port 1 (s1), serial port 2 (s2), and serial port 3 (s3). remote attachment through modem is supported on serial port 1 (s1) and serial port 2 (s2).
