Those two sentences have little to do with one another.  Perhaps the
PR's subject was misleading; "ftp ignores some settings of eofc" might
have been more accurate.

I'm fairly sure I am.  See the original PR, or relevant excerpts below.

> You didn't specify that you had set EOF to something odd

query-pr's output differs on this point.  See below.

> (^Z is not ASCII EOF!)

There is no EOF character in ASCII, as far as I can tell; EOT - ^D - is
arguably the closest, though a case could perhaps be made for ETX.  Be
that as it may, I choose to use SUB - ^Z - for my eofc (largely due to
a VMS heritage back in my larval stage), and PR 3982 arose because
something in ftp, almost certainly libedit, breaks this - ^Z does not
function as EOF at the ftp command line for me, despite being my eofc
and working Just Fine in most respects (even, as noted below, gdb,
which *also* provides command-line editing).

Here are those excerpts from "query-pr --full 3982", as run on a few minutes ago:

| >Description:

| 	both should be divorced from the EOF-character functionality).
