Console features

HMC applets

You can use two applets.

Operating System Messages

This applet provides a line-mode terminal for Linux® in LPAR mode. See Figure 1 for an example.

Integrated ASCII Console

This applet provides a full-screen mode terminal for Linux in LPAR mode and for Linux on z/VM®.

These HMC applets are accessed through the service-call logical processor (SCLP) console interface.

3270 terminal

This terminal can be based on physical 3270 terminal hardware or a 3270 terminal emulation.

z/VM can use the 3270 terminal as a 3270 device or perform a protocol translation and use it as a 3215 device. As a 3215 device it is a line-mode terminal for the United States code page (037).

The iucvconn program

On Linux on z/VM, you can use the iucvconn program to access terminal devices on other Linux instances that run as guests of the same z/VM system.

See How to Set up a Terminal Server Environment on z/VM, SC34-2596 for information about the iucvconn program.

virsh command on the KVM host

For Linux on KVM, you can access the console through a virsh command on the KVM host. See Using virsh on a KVM host.

The console device drivers support these terminals as output devices for Linux kernel messages.
