The Orbiter configuration file will hold additional parameters at its end like so:

 ; === Base Vessel Configuration ===
 BaseScenarioSave = TRUE
 BaseRecorderSave = TRUE
 BaseAutoSpawn = TRUE
 BaseFastReset = TRUE
 ATCAnnotationSlot0 = 0.200000, 0.100000, 0.800000, 0.200000
 ATCAnnotationSlot1 = 0.200000, 0.200000, 0.800000, 0.300000
 ATCAnnotationSlot2 = 0.200000, 0.300000, 0.800000, 0.400000
 ATCAnnotationSlot3 = 0.200000, 0.400000, 0.800000, 0.500000

The Base* entries simply reflect the corresponding settings in the extra dialog for base settings. These settings will always be there at least with the defaults.

The ATCAnnotationSlotX entries contain the ATC text slot coordinates for slot X (starting from zero). The parameters are comma-separated values between 0 and 1, specifying the position of left border, upper border, right border, lower border (in that order), where 0 is the left (or upper) screen border and 1 is the right (or lower) screen border. These settings will not be in the configuration automatically as of f6b296b8287bb5e70921d693a4fcadedc4078540 , as the default is to have no slots at all (and thus no ATC text displayed). You have to edit it manually.

Given the above slot definition, expect something like this for ATC chatter:
