Surprise! If you put "Never" or "Nvr" or "DON'T" in the second field of
the /usr/lib/uucp/Systems file (HDB only), it will consider it the SAME AS
"Any". Yes, people on your system can poll those long distance sites! Ok,
go ahead do a strings on /usr/lib/uucp/uucico and look around the "Su", "Wk"
and "Any" strings. Don't see "Never" there do you? Well, there is a solution.
There is an optional subfield on the time field, which when present substitutes
a fixed retry time for the normal, exponential back retry time. When this
subfield is present, the lack of a legal time string works the same as "Never"

Sooo, if you wanted this:
---
system Never ACU Any - don't call this system, let them call us
---

use this:
---
system ; ACU Any - don't call this system, let them call us
---

Old uucp had a "," subfield, but it was for a different purpose
