Thats slightly different, printed for tomorrows experiments. Thank you.
I need to reboot to bring in a fresh kernel that was updated earlier
today. But I'm out of giddy-up, haveing repaired a dishwasher MCU based
control module today in my own dishwasher. The parts houses for such
wanted 266.55 USD for one that may, or may not have had the same
software. But I found 3 of the teeny electrolytics in it, 10 u-f at 16
volts, were reading at about .02 u-f, so now there are a triplet of 10
u-f x 16 volt tantalum caps in it. I don't enjoy working on a pcb that
has no schematic, not even online, but then I am also a C.E.T.
(Certified Electronics Technician), but will plead to quit a bit of rust
in the wet ram (its 81 yo now) in the 44 years since I sat down cold
without cracking a book, to take that test back in '72.

In normal everyday operation, the variable ${InMail} will not be empty.
