Description of problem:
The stty command does not effectively change terminal line settings. An 'stty
erase CHAR' command, for instance, causes the CHAR to appear in an 'stty -a'
listing but the CHAR does not actually perform an erase. This method of changing
key/command bindings appears to have no effect in either tcsh or csh in RedHat
Linux 7.x. In the sh shell, the bindings change to match those displayed in an
'stty -a' listing but only after the shell is re-invoked. So, 'stty erase CHAR'
will not cause CHAR to start erasing the last character typed but executing 'sh'
again after this command will.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Type 'stty -a'. Note the settings (e.g. erase = ^?).
2. Type a command to change a stty setting (e.g. type 'stty erase p').
3. Type 'stty -a' again. Note that the output has changed (e.g. erase = p)
4. Type the new command character. Note that its powers have not been changed by
your stty command. (e.g. 'p' prints a 'p' to the screen; it does not erase)
Actual Results: The key/command bindings listed by an 'stty -a' did not match
the actual key/command bindings in my shell.
Expected Results: If I typed 'stty erase p' as in my example above, causing an
'stty -a' to list p as the erase command key, then the future effect of typing a
'p' should have been to erase the last character typed.
I also encountered this stty problem in tcsh on a Compaq Alpha running Tru-64
digital Unix. However, on that machine, the problem was not present in csh or
sh. So, this problem may be enhanced by tcsh.
Possibly a readline problem. For example, if you run 'cat', stty settings are
honoured. The difference is readline. (But bash might not be hooking into
