Configuring Your System
Save these settings in a file. For example, settings for the EB64 could be saved in a
file called eb64.trm.
For consistency, all examples and command descriptions assume that the
motherboard serial port 1 is connected to COM1.
2.3.4 Connecting from a System Running DIGITAL UNIX
DIGITAL UNIX supports serial communications and Ethernet communications with
the motherboard.
An Alpha system running the DIGITAL UNIX operating system supports serial
communication through the following two ports that can be connected to the
motherboard:
• /dev/tty00
• /dev/tty01
For consistency, all examples and command descriptions assume that the
motherboard serial port 1 is connected to port /dev/tty00.
To enable these ports for use with the motherboard, follow these steps:
1. Log in as superuser.
2. Modify the following two files:
/etc/remote
/etc/inittab
a. Add the following two lines to the /etc/remote file. These lines define a
device to connect to when using the DIGITAL UNIX tip command.
port_name0 :dv=/dev/tty00:br#9600:pa=none:
port_name1 :dv=/dev/tty01:br#9600:pa=none:
The port_name refers to an arbitrary name that you assign to that port.
b. Modify the /etc/inittab file to disable logins on the two serial
communication ports by setting the third field to off. For example, modify
the tty00 and tty01 lines as follows:
tty00:23:off:/usr/sbin/getty /dev/tty00 9600
tty01:23:off:/usr/sbin/getty /dev/tty01 9600
3. Reboot the system or issue the following command to ensure that the modified
files take effect:
# /sbin/init q
