Perhaps a simpler example:

under telnet to localhost in September2-current:
$ cat
123^D
[the ^D is echoed and no newline is printed]
123SENT IAC EOF
[another ^D causes the message to overwrite the echo of the first ^D and a
 newline is printed]
SENT IAC EOF
123
[results of a third ^D.  No newline]
123SENT IAC EOF
$
[results of a fourth ^D.  The 123 is from the previous ^D].

Normal syscons tty:
$ cat
123123
[^D after 123 causes `cat' to read "123" and echo it like it should]
$
[second ^D causes `cat' to read EOF like it should].

The tty settings are the same except for the speed and `extproc'.
