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
undef disables that
special character. (This is incompatible with Ultrix
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.)
