Hi, Oldes,
Looks like it is currently used in the echo command:
>> source echo
echo: func [
"Copies console output to a file."
[catch]
target [file! none!]
][
if port? system/ports/echo [
close system/ports/echo
system/ports/echo: none
]
if file? target [
system/ports/echo: throw-on-error [open/write/new/direct target]
]
]
I was originally thinking it might be used in serial communications, like
setting echo on or off, etc. Maybe it is, but I can find no use that proves
this point.
For what its worth. Regards,
