Either the Start Time or the Stop Time may be replaced with a semicolon, in which case that item will
be unchanged by the command.
Sample entry: F26 ; XXX:XX:10:00.000<CR>
Response: OK<CR><LF>
This entry will leave the Start Time set to whatever it was before, and will change the Stop Time to
10 minutes after the hour. If both the Start Time and the Stop Time match the current time, then the
pulse is turned off.
Sample entry: F26 XXX:XX:XX:XX.2XX XXX:XX:XX:XX.XXX<CR>
Response: OK<CR><LF>
The pulse would normally be turned on every second at 200 milliseconds, but the Stop Time also
matches then, so the pulse will stay off.
To clear the output regardless of the time: F26 000:00:00:00.000 XXX:XX:XX:XX.XXX
To set the output regardless of the time: F26 XXX:XX:XX:XX.XXX 000:00:00:00.000
The default power-on Pulse Out setting is: F26 000:00:00:00.00 000:00:00:00.000
Since the day is day 000, the Start and Stop times never match.
When the power is turned off, the current setting is saved in non-volatile memory, to be restored when it
is next turned on.

or tab
<MODE> = either TI for Time Event or ET for Event Timing (this field is
optional with the default being ET)
