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. -- "If that's true, then I'm the Pope!" Stephen J.

We finally figured it out. Somehow /dev/tty had lost read permission for group and other. -- "If that's true, then I'm the Pope!" Stephen J. Hartley USENET: decvax!dartvax!uvm-gen!uvm-cs!hartley The University of Vermont CSNET: hartley%uvm@csnet-relay (802) 656-3330
