* Protocol 1001
*
* OMNIVS Commands: (capital letters are literals, lower-case are variables)
* :B -> Bxxxxyy (xxxx/55.0: Hz in, yy/16: battery voltage)
* :F -> F1143_A (where _ = \0) Firmware version?
* :L -> LvvvvXX (vvvv/2.0: VAC out)
* :P -> P01000X (1000VA unit)
* :S -> Sbb_XXX (bb = 10: on-line, 11: on battery)
* :V -> V102XXX (firmware/protocol version?)
* :Wt -> Wt (watchdog; t = time in seconds (binary, not hex),
* 0 = disable; if UPS is not pinged in this interval, it
* will power off the load, and then power it back on after
* a delay.)
*
* % % % % % % % % % % % % % % % % % % % % % % % % % % % % % % % % % % %
*
* The outgoing commands are sent with HID Set_Report commands over EP0
* (control message), and incoming commands are received on EP1IN (interrupt
* endpoint). The UPS completely ignores the conventions of Set_Idle (where
* you NAK the interrupt read if you have no new data), so you constantly have
* to poll EP1IN.
*
* The descriptors say that bInterval is 10 ms. You generally need to wait at
* least 80-90 ms to get some characters back from the device. If it takes
* more than 250 ms, you probably need to resend the command.
*
* All outgoing commands are followed by a checksum, which is 255 - (sum of
* characters after ':'), and then by '\r'. All responses should start with
* the command letter that was sent (no colon), and should be followed by
* '\r'. If the command is not supported (or apparently if there is a serial
* timeout internally), the previous response will be echoed back.
*
* % % % % % % % % % % % % % % % % % % % % % % % % % % % % % % % % % % %
*
* SMARTPRO commands (3003):
*
* :A -> ? (start self-test)
* :D -> D7187 (? - doesn't match tripplite.c)
* :F -> F1019 A firmware rev
* :H__ -> H (delay before action?)
* :I_ -> I (set flags for conditions that cause a reset?)
* :J__ -> J (set 16-bit unit ID)
* :K#0 -> (turn outlet off: # in 0..2; 0 is main relay)
* :K#1 -> (turn outlet on: # in 0..2)
* :L -> L290D_X
* :M -> M007F (min/max voltage seen)
* :N__ -> N
* :P -> P01500X (max power)
* :Q -> (while online: reboot)
* :R -> R<01><FF> (query flags for conditions that cause a reset?)
* :S -> S100_Z0 (status?)
* :T -> T7D2581 (temperature, frequency)
* :U -> U<FF><FF> (unit ID, 1-65535)
* :V -> V1062XX (outlets in groups of 2-2-4, with the groups of 2
* individually switchable.)
* :W_ -> W_ (watchdog)
* :Z -> Z (reset for max/min; takes a moment to complete)

* The SMARTPRO unit seems to be slightly saner with regard to message
* polling. It specifies an interrupt in interval of 100 ms, but I just
* started at a 2 second timeout to obtain the above table.

* :K1 -- turns on power receptacles
* :K0 -- turns off power receptacles
* :G -- unconfirmed: shuts down UPS until power returns
* :Q1 -- enable "Remote Reboot"
* :Q0 -- disable "Remote Reboot"
* :W -- returns 'W' data
* :L -- returns 'L' data
* :V -- returns 'V' data (firmware revision)

* :D -- returns general status data
* :B -- returns battery voltage (hexadecimal decivolts)
