the nodelist flag for vmodem is IVM ;)  those old ones that were not prefixed
by "I" are obsolete and no longer used in the distributed nodelist... some
abandoned software still in use may still require them, though... it should
also be noted that ITN should not be used unless there is a mailer on telnet...

Once men turned their thinking over to machines in the hope that this would set
them free. But that only permitted other men with machines to enslave them.
