I am trying to modify rlogin and rlogind to allow people to run a screen oriented version of sas without logging in. We are running version 9.0 of convex unix on the rlogin machine. We want people to run sas on that machine and have it look as though it is actually on that machine (there isn't a version of sas for convex which is the root of the problem). The other machine is going to be dedicated to running sas and is running ultrix v4.1. The problem is that the line that is opened is not being made to be the control terminal. Sas works OK if it is told to use stdin and stdout, but will not use its screen oriented format. When it trys to use the screen oriented format it insists on using /dev/tty. But since there is no control terminal this doesn't work. According to the information I have found, just opening a terminal should make it the control terminal (if you don't already have one and it isn't being used by someone else). In trying to play around with the problem it looks like the tty that is associated with the pty opened by the modified rlogind program is not being treated as a terminal device. I would appreciate any help on this problem.
