When a trigger condition is met, the add-on outputs pre-defined text string
to PC's serial port to control external devices or display, which include
various devices listed under Windows Device Manager's COM group, such as
USB to RS-232, RS-485/422 converter.
customer contacted us with his application:

temperature goes too high, or amps go too high, a serial string goes
I'm doing battery testing. I need a good way to stop it when I hit a
certain set point, or input is actuated.
Basically, when volts is too low, amps is too high, stop-test button
is hit or temp is too high, send "LOAD OFF" to the serial
When start button is hit, send "LOAD ON" to the serial port.
Would be nice to be able to define the string or multiple strings with
