Tests The Post Runs - Sun Microsystems SPARCclassic Service Manual

workstation or server system). This connection lets you use a shell window on the
Sun workstation as a terminal to the SPARCstation 10 being tested.
The tip method is recommended, because it lets you use SunOS windowing and
operating system features to help you work with the boot PROM.
To make a tip connection, follow these steps:
1. Connect the system's serial port (ttya) to another Sun workstation ttya serial
port using a serial connection cable. This connection is made with a 3-wire null
modem cable. Connect wires 3-2, 2-3, and 7-7.
2. At the other Sun workstation, add the following lines to the file /etc/remote:
hardwire:\
:dv=/dev/ttya:br#9600:el=^C^S^Q^U^D:ie=%$:oe=^D:
3. In a Shell Tool window on the Sun workstation, type tip hardwire. (Some
commands will not work properly in a Command Tool window.)
The system will reply connected.
hostname% tip hardwire
connected
The Shell window is now a tip window directed to the Sun workstation serial
port.
4. When you are finished running POST and want to disconnect the tip window,
type kill -9 and the process ID number of the tip hardwire process.
hostname% kill -9 PID# of tip hardwire process
