These commands are used to set the interval for the Arm Layer 2 and Trigger Layer timers. Note
that the timer is in effect only if the timer is the selected control source. Also, note that Arm Lay-
er 1 does not use a timer.

Line 10 Sets the Trigger Layer timer for a 1/4 second interval, and then queries the pro-
grammed timer interval.
Line 20 Addresses the 7001 to talk.
Line 30 Displays the timer interval (.25).
