The screen setup should be changed as follows:
% setenv TERM vt100
If the screen suddenly stops and nothing happens any longer, this may indicate that you
accidentally
hit <CTRL><S> (screen stop). The screen lock can be removed as follows:
<CTRL><Q>
If the screen becomes inactive and nothing happens any
longer, this usually indicates that
another program is running.
Most programs can be killed as follows:
(direct)
or
If the
screen
displays all your input without taking any action, another
program may be running (e.g., the
editor, which is used to modify data files).
To exit an editor program,
try the following:
For mail, etc.
<ESC><:><q><!>
If you have no <ESC> key, try <CTRL><3> instead.
<CURSOR>:
In some sessions across the network, the <CURSOR> keys either have no effect at
all or result in
^]A
or similar. Make sure that you are running the most
recent version
of the operating system and terminal emulation software.
On PCs, the program manual should explain how to use cursor keys.
On systems running VMS
or UNIX, the terminal setting may be
wrong. Some PC terminal emulators are known to have
problems with the cursor keys.
<DELETE>:
In some sessions across the network, the delete key may produce
^?
(or similar) or jump to the beginning of the line. Make sure that you
are running the
most recent version of the operating system and terminal
emulation software.
On PCs, the program manual should explain how
to use <ERASE> and <BACKSPACE>
keys instead of <DELETE>. On
systems running VMS or UNIX, <CTRL><H> might
work as well.
Any key can be re-mapped to the <DELETE> key as
follows (press the
current <DELETE> key after the word "erase"):
% stty erase ^?
If you work on DEC's family of keyboards, try:
% stty dec
National character sets are a notorious source of oddities. E.g., the pipe symbol (|)
is difficult to find on Swiss keyboards and occasionally prints as national
u(umlaut) on Swiss
screens. Depending on your terminal or terminal
emulator, there are ways around this by setting
the communication
line to eight bit. Other solutions include the re-mapping of the
keyboard,
but this should be left to system specialists.
WORKAROUND
Due to some technical problems
with localised keyboards it might be difficult
for you to
display the characters "{" and "}" by typing the corresponding
characters on the keyboard.
The only option to survive is
to find the character elsewhere and transfer it.
E.g., use the command 'genhelp distances
example' and
use the COPY option of your terminal or terminal emulator to take the {*}
into
the Paste buffer. PASTE the resulting keystrokes where appropriate.
In some
cases, the software you want to use does not work because a previous session is still
active
or has been terminated abnormally. Programs like 'nn' or 'seqed' are known to
create so-called
'lock'-files which need to be removed in order to
restart a session. Refer to section
"File Handling Commands"
in order to delete such a file.
