next in thread | raw e-mail | index | archive | help
First change is a bug fix in syscons.c:
sequence 'ESC [ n X' now work
Second change append SCO console like font changing:
ESC [ 10 m - selects the primary font
ESC [ 12 m - selects seconds alternate font; toggles
high bit of extended ASCII code before
displaying as ROM sharacters
ESC [ m
ESC [ 0 m + selects the primary font
