> > that is not a ksh/ast error message
the statement is correct
but its the wrong observation
"not on an active synchronous line" is written to the standard output
its not an ksh/ast error message for two reasons
not written to standard error and not prefixed by "command: "
so to find out why this message is printed using ksh93
find the { $ENV /etc/*rc* .profile } file that calls "tty -l"
and then we can determine why ksh93 sources that file and not-ksh93 doesn't
thanks for the tty -l ref
