A couple of weeks ago, I posted question about P_ZERO in my uucp chat
scripts. Basically everyone said the same thing, although I did receive
the following.

| connection to some non-Sun machine; it won't log in. What's wrong?
| The 4.1[.x] UUCP normally runs in even-parity mode when logging
| into another machine. If the other machine is running in 8
| bits, no parity, mode, the fact that the 8th bit is set on some
| of the characters the Sun is sending to it will confuse it.
| The Sun can be made to turn the 8th bit off by putting P_ZERO in
| the appropriate place in the appropriate UUCP configuration file
| [I may have been the one to put P_ZERO there, but I forget the
| details; it's in the send-expect sequence in the Systems file
| entry for the machine, and I think you have an "expect" string
| of "" - i.e., "expect nothing" - and a "send" string of P_ZERO -
| i.e., make the parity bit zero. Check the UUCP stuff in the
| "Systems and Network Administration" document to make sure.]
