InfoConnect for Airlines VBA Guide
AllowColorTableChanges Property
Gets or sets whether InfoConnect responds to host commands that are related to color table changes.
Object.AllowColorTableChanges As Boolean
When this property is set to true, the terminal color map can be set using either the ReGIS S(M) command or the restore color table (DECRSTS) control function. When this is set to false, InfoConnect does not change the color table in response to these commands.

InfoConnect always allows the color table to be changed as a result of displaying a sixel, regardless of the value of AllowColorTableChanges. The default value is true.
