1	Lab Switch control utility
2	--------------------------
3
4	If invoked without arguments, labsw prints the firmware version and
5	build date.
6
7	The following commands can be given on the command line:
8
9	ch1=0, ch1=1, ch2=0, ch2=1
10	turn the respective channel on or off. Both relay and
11	opto-coupler are switched. Also enters remote mode.
12
13	query
14	read the buttons and opto-coupler inputs (rear panel)
15
16	local
17	exit remote mode
18
19	The Lab Switch starts in local mode, where the CH1/CH2 buttons
20	toggle the respective channel. The main button turns off both
21	channels. Local mode is indicated by a green main LED.
22
23	If a channel is set via USB, the Lab Switch enters remote mode,
24	indicated by a red main LED. In remote mode, the channel buttons
25	are ignored. Pressing the main button exits remote mode and
26	turns both channels off.
27
28	The lab switch utility currently lacks the following features:
29	- access to the rear opto-coupler outputs,
30	- switching CH1/CH2 relay and opto-coupler independently,
31	- direct control of LEDs.
32
33	Examples:
34
35	# labsw ch1=1
36
37	Turns channel 1 on and enters remote mode.
38
39	# labsw ch1=0 ch2=0 local
40
41	Turns channels 1 and 2 off and exits remote mode. This is
42	equivalent to pressing the main button.
