The adapter I'm using is a DB25->RJ11 (6P6C) wired to pass TX/RX and
RTS/CTS in "null-modem" fashion. DTR is looped back onto both CD and
DSR.  The cable is only 4-line flat phone cord so only TX/RX and GND go
through.

Again, this works fine on NetBSD-8_STABLE.

I recall something about needing a valid CTS signal, so I rewired it to
locally loop RTS<->CTS.  That definitely allowed characters out as I
watched (via 'ps' from SSH connection) the waiting 'sudo' abort.

But I'm not receiving any input either.  That has me even more puzzled.
