I'm having a problem with the R4 xterm on MIPS RISC/os 4.0 having to do
with /dev/tty.  If I rlogin to the mips machine (i.e. /dev/tty is
connected) and run xterm, /dev/tty is ok in the xterm.  If I use rsh
instead, as in
  rsh mips-machine xterm
the xterm does not have a /dev/tty available to it.  I've tried all the
combinations of TIONOTTY, and closing and opening ttys, and setpgrp()
that I can think of, but I've been unable to fix this problem.  I notice
that the MIPS version of xterm (licensed for a different machine here)
does not have this problem.  I'm using SYSTYPE_BSD for compiling.

Has anyone else seen this problem?  Any ideas?  I'm starting to think
there's a bug in RISC/os itself, but tty and termio documentation and
the xterm main.c being what they are, it's sort of hard to generate
a usable bug report to MIPS.

Thanks for any advice,
