S2-3: Extended Signaling Rate
The setting for switch S2-3 determines the range of variability
the Model 1140 "looks for" in asynchronous data rates (i.e., the
actual variance from a given frequency level the Model 1140 will
tolerate).
S2-3 Setting
Off
-2.5% to +1% Basic
On -2.5% to +2.3% Extended
S2-4 and S2-5: RTS/CTS Delay
The combined settings for switches S2-4 and S2-5 determine

and when it sends CTS. Options are no delay, 7 ms and 53 ms.
