|I recently compiled emacs version 18.54 on a Sequent Symmetry running DYNIX
|V3.0.12.

|When I now in the Sequent window type "emacs -nw" emacs starts up ok and seems
|to perform allright. However, when I just do "emacs &" emacs opens a window,
|loads .emacs and then just sits there totally unresponsive, not even the cursor
|box fills when moving the mouse inside the emacs window. When typing to the
|window the process after a while exits with a status of 1 after displaying
|the message:
|"XIO:  fatal IO error 50 (Network is down) on X server "scesaplana:0.0"
|      after 25923 requests (41 known processed) with 0 events remaining."

I had the same experience. The following patch to m-symmetry.h (or m-sequent.h)
makes the problem go away:

    sprintf (ptyname, "/dev/tty%c%c", PTY_MAJOR[ma], PTY_MINOR[mi]);
  
  #define STACK_DIRECTION -1
