I just checked in and created a pull request for turning OS Ticks printing
on/off.
?
Commands:
echo ? prompt ticks tasks mempools
date b
ticks on
248940:Ticks set to:
248940: Console Ticks on
prompt on
249600: Prompt now on.
249600: > ticks off
Console Ticks off
> prompt off
Prompt now off.
I also updated the prompt command to be able to turn it off, which apparently
you couldn't do before once it was on.
This can also be set in syscfg.yml as CONSOLE_TICKS 1 (or 0 to turn it off)
