Specifying a Separate System Console

Specifying a Separate System Console

In order to use the standalone debugger, you must have an ASCII terminal as a separate system console device. Install a terminal next to the system or workstation and connect it to the first serial port. Verify its operation as a terminal by logging in to the system. You may have to modify the file /etc/inittab so that the line for the alternate console is active (see the inittab(4) reference page).

When you have verified that the terminal works, use the nvram command to change the nonvolatile RAM variable console from a letter "g" to a letter "d," as follows:

# nvram console
g
# nvram console d
# nvram console
d

The nvram command is used to report and change the contents of the nonvolatile RAM variables used by the boot PROM and standalone shell (see the nvram(1) reference page).
