Damien already added a config option ("RequestTTY") but there hasn't
been a release since then (this problem didn't become apparent until
after the 5.8 release when people used it with the problem devices).
Specifies whether to request a pseudo-tty for the session. The
argument may be one of: ``no'' (never request a TTY), ``yes''
(always request a TTY when standard input is a TTY), ``force''
(always request a TTY) or ``auto'' (request a TTY when opening a
login session). This option mirrors the -t and -T flags for
