4.2 script mystery problem

[Stephen J. Hartley]

  The program script has stopped working on our 750 (still works on our 780).
It types out "Script started, file is typescript" then "Stopped (tty input)".
As best as I can tell the forked shell is trying to read from the terminal
rather than a tty pseudo-device.  I tried removing them all and then "MAKEDEV
pty0" in /dev but the problem persists.  Is there some way that the pseudo-
terminals can stop working that anybody knows of?  We run 4.2 BSD on both
machines.  The pty's are configured into the kernels of both machines, along
with the INET option.  A reboot does not fix the problem.  Script worked on
both machines for a while, then quit on just the 750.
  Another clue:  crypt key <infile >outfile works on the 780 but not on the
750.  On the 750, crypt tries to obtain the key from stdin (infile) rather
than prompting from /dev/tty.
  Does anybody have any idea what might be going on here?  Thanks.
