HP_TERMINAL_ATTRIBUTE_HANDLING

When set to 1 (on, true, yes), if the previous character was written to a line other than the current one this variable causes the runtime to set the attribute for the character to be written even if the attribute has not changed. When set to 0 (off, false, no), this variable causes the runtime to behave as it always has. For example, if the terminal attribute has not changed then it will not be set again. The default setting is 0 (off, false, no).
