Chapter 3 Power-On Self-Test (POST) 3-5
3.4.1 Setting Up a tip Connection to Another
Workstation
You can use the serial port on your SPARCstation to connect to another Sun
workstation (either the same type of SPARC system or a different type of Sun
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:
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.
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.
hardwire:\
:dv=/dev/ttya:br#9600:el=^C^S^Q^U^D:ie=%$:oe=^D:
hostname% tip hardwire
connected
hostname% kill -9 PID# of tip hardwire process
