acsUse the Alternate Character Set to draw the border. The border is drawn using character line graphics if the terminal supports them.

boldUse extra bright or bold mode.

set tui tab-width ncharsSet the width of tab stops to be nchars characters. This setting affects the display of TAB characters in the source and assembly windows.
set tui compact-source [on|off]Set whether the TUI source window is displayed in “compact” form. The default display uses more space for line numbers; the compact display uses only as much space as is needed for the line numbers in the current file.

set debug tui [on|off]Turn on or off display of GDB internal debug messages relating to the TUI.
show debug tuiShow the current status of displaying GDB internal debug messages relating to the TUI.
Note that the colors of the TUI borders can be controlled using the
appropriate set style commands. See Output Styling.
