Automatic Timeout
The COS II times the intervals between the reception of each character and the next. You may instruct it to return to an unlinked state after intervals of 2.5, 5, or 10 minutes, or you may disable this automatic timeout feature. SWF 5 and SWF 6 control this feature.

Graphics Pause
These switch settings are followed only when the COS II has been set previously for Graphics Mode (for an explanation, see Section 4.5). They determine the amount of time that must pass before the COS II recognizes a control code sequence.
By providing for this pause, it is possible to send graphics files through the unit with no risk that it will switch accidentally when it encounters a control code sequence, or its binary equivalent. SWF 7 and SWF 8 determine the length of the pause.
