19.2.6 Special characters

The special characters' default values vary from system to system. They are set with the syntax `name value', where the names are listed below and the value can be given either literally, in hat notation (`^c'), or as an integer which may start with `0x' to indicate hexadecimal, `0' to indicate octal, or any other digit to indicate decimal.

For GNU stty, giving a value of ^- or undef disables that special character. (This is incompatible with Ultrix stty, which uses a value of `u' to disable a special character. GNU stty treats a value `u' like any other, namely to set that special character to U.)

`quit'
Send a quit signal.

`erase'

`kill'

`eof'
Send an end of file (terminate the input).

`eol'
End the line.

`eol2'
Alternate character to end the line. Non-POSIX.

`swtch'
Switch to a different shell layer. Non-POSIX.

`start'
Restart the output after stopping it.

`stop'
Stop the output.

`susp'
Send a terminal stop signal.

`dsusp'
Send a terminal stop signal after flushing the input. Non-POSIX.

`rprnt'
Redraw the current line. Non-POSIX.

`werase'
Erase the last word typed. Non-POSIX.

`lnext'
Enter the next character typed literally, even if it is a special character. Non-POSIX.
