Many UUCICOs cannot dial into systems that require parity (such as OUR non-
native UNIX system).  4.2BSD supposedly allows one to specify parity, but
it isn't in Sun's UUCICO.  I hacked our UUCICO to allow specifying parity.
Some UUCICOs will accept 8 bits in send strings so that if you do your
own parity generation, e.g. "he\314\314o" for hello it will work.  I have
the table if anyone wants it.  Not all UUCICOs accept \(3 octal digits).

Have the called system's uucp account & password be such that the parity
bit for all characters is 0.
