Re: backspace is not working
the backspace at unix level is working properly,i compered the output of stty -a on two system and i found no difference.
the problem with backspace is inside the 4gl program,after rebooting the system the program works fine for 2 hours . then the backspace stop working, (it should move to a previous page in the program)
how to reload the termcap to the kernel???

Re: backspace is not working
You can press the Ctrl key and the h key at the same time for backspace until you figure out your termcap issue. Good Luck.

The problem would appear to be in your program. Perhaps it is corrupting it's own variables. I suggest when the problm appears that you terminate and restart your program (not the whole server). The 'terminfo' ('termcap') files are not loaded into the kernel.

Re: backspace is not working
So to rule out the emulator, check the settings to see if the emulator changed. If all is well (backspace = backspace) then see if the pty device has been changed. stty can be called by any program so (badly written) code may be changing the setting. Use stty -a and connect it to the pty device with the problem.
