Hi Jonathan. I am having a problem that relates to the patch that you helped me with. I copy a message which I just posted to -questions. Because this is a new problem to me, I wondered about the patch that you made me aware of; So I put the old modules back in to check, and the problem, went away (and of course the original problem, of some time ago, came back) Here is a copy of my post; ------------------------------ I am running a SCO program which seems to run fine. When I exit back to the shell my prompt does not behave properly at the console. Each time I hit return there is no line feed. It looks like this; bash-2.03$ bash-2.03$ bash-2.03$ and so on. My typing will not appear on the screen, but the commands are effective. I have tried other shells, with the same effect. I also have tried running the same test on a serial terminal, and this does not pose a problem. The problem does not seem to be machine oriented. I took the hard drive out, and installed it in another machine and the new machine's console shows the same problem. Any idea what could be causing this? -------------------------------- The problem does not seem to effect X It would be great to get your idea of what's going on. For your reference the past is below; -------------------------------------------------- On Wed, May 23, 2001 at 09:14:00AM +1200, Jonathan Chen wrote: > On Tue, May 22, 2001 at 04:11:15PM +0000, David Banning wrote: > > > But, this database program hangs when it comes time > > > for the opening screen. > > > > Yes. > > > > > > > > My guess is that the database program is doing something during > > > the opening screen that has nothing whatsoever to do with the > > > terminal session, but is making the process crash.
