S1-3 through S1-6:  Not Used

S1-7 and S1-8:  RTS/CTS Delay

The combined settings for switches S1-7 and S1-8 determine the

amount of delay between the time the Model 1018RC “sees” RTS and
when it sends CTS.  Currently, the Model 1018RC does not have
optional delay settings.  “No Delay” is defined as between 500 nsec and
1 msec.  The switches should remain in the “OFF” position.
