Working with Linux terminals

Red Hat Enterprise Linux 8.6 LPAR mode z/VM guest KVM guest

You might have to work with different types of Linux terminals, and use special functions on these terminals.

Using the terminal applets on the HMC
You should be aware of some aspects of the line-mode and the full-screen mode terminal when working with the corresponding applets on the HMC.
Accessing terminal devices over z/VM IUCV
Use z/VM® IUCV to access hypervisor console (HVC) terminal devices, which are provided by the z/VM IUCV HVC device driver.
Switching the views of the 3270 terminal device driver
The 3270 terminal device driver provides a terminal with three different views for Linux on z/VM.
Setting a CCW terminal device online or offline
The 3270 terminal device driver uses CCW devices and provides them as CCW terminal devices.
Entering control and special characters on line-mode terminals
Line-mode terminals do not have a control (Ctrl) key. Without a control key, you cannot enter control characters directly.
Using the magic sysrequest feature
The Linux on IBM® Z terminal device drivers support the magic sysrequest functions.
Using a z/VM emulation of the HMC Operating System Messages applet
You can use the Operating System Messages applet emulation; for example, if the 3215 terminal is not operational.
Using a 3270 terminal in 3215 mode
The z/VM control program (CP) defines five characters as line-editing symbols. Use the CP QUERY TERMINAL command to see the current settings.
