Setting Up a
tip
Connection to Another
Workstation
You can use the serial port on the SPARCstation Voyager workstation 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 Voyager workstation
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.
1. Connect the SPARCstation Voyager workstation 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 shelltool 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
