See my post on this subject.  It's plain wrong.

However, if you turn on XON/XOFF in a Telebit modem and use spoofing
(S111-30), it is smart enough to disable it when a uucp call comes in or
out.  Thus, it works for both interactive users AND UUCP calls.

This is not obvious, but it does work.  I do it that way myself on one
modem, the other I wired strange for full modem control (CTS/RTS + modem
control) since it has V.32 capability and you need it there.
