A.3 Using the vt220 Terminal
Emulator
Recent MicroCode Levels allow the use of an integrated vt220 terminal emulator in
addition to the standard line mode terminal. The vt220 terminal is connected to
/dev/
ttyS1
. The line mode terminal is connected to
/dev/ttyS0
.
To activate vt220 support on your machine, edit
/etc/inittab
as user
root
. Look
for the following line and delete the leading
#
sign:
# 2:2345:respawn:/sbin/mingetty --noclear /dev/ttyS1 linux
Save the file and run
telinit q
to pass the changes in
/etc/inittab
to init. The
vt220 terminal should then be ready to use. If not, try hitting
Enter
at the terminal until
the login prompt appears.
As soon as the vt220 emulation is available, an icon for an integrated vt220 ASCII
console appears next to the icon for the 3215 console on the HMC/SE. Make sure that
you do not apply the changes as described above to a system that does not support vt220
terminal emulators. Otherwise, login might become impossible on this system and you
will be shown the following message:
INIT respawning too fast, disabled for 5 minutes.
To redirect the kernel messages at boot time from the system console to the vt220 ter-
minal, add the following entries to the
parameters
line in
/etc/zipl.conf
:
console=ttyS0 console=ttyS1
The resulting
parameters
line would look like the following example:
parameters = "root=/dev/dasda2 TERM=dumb console=ttyS0 console=ttyS1"
Save the changes in
/etc/zipl.conf
, run
zipl
, and reboot the system.
