1. Connect serial port A of the system being tested to another Sun Workstation serial
port B using a serial null modem cable (connect cable pins 2-3, 3-2, 7-20, and 20-7).
2. At the other Sun workstation, check the /etc/remote file:
hardwire:\
:dv=/dev/term/b:br#9600:el=^C^S^Q^U^D:ie=%$:oe=^D:
Note – The example shows connection to serial port B, ttyb
3. To use serial port A:
a. Copy and paste the following:
hardwire:\
:dv=/dev/term/b:br#9600:el=^C^S^Q^U^D:ie=%$:oe=^D:
b. Then modify as follows:
hardwirea:\
:dv=/dev/term/a:br#9600:el=^C^S^Q^U^D:ie=%$:oe=^D:
4. In a shell tool window on the Sun Workstation, enter tip hardwire.
The system replies:
hostname% tip hardwire
connected
Note – The shell window is now a tip window directed to the serial port of the
Sun Workstation or server being tested. When power is applied to the system being
tested, POST messages will be displayed in this window.
5. When POST is completed, disconnect the tip window as follows:
a. Open a shell tool.
b. Enter ps -a to view the active tip line and process ID (PID) number.
