(i.e. Resizes automatically on window >resizes etc...) The necessary hooks to do this are already in most systems. To have it work, your system must do several things right: 1) xterm must give a new window size to the pty with the TIOCWINSIZE (or something like that) ioctl. 2) The tty driver must give a SIGWINCH to the current process when it's winsize changes. 3) vi must trap the SIGWINCH and redraw. Most vi's do this. It will work correctly on BSD 4.3. The ioctl #define is different between BSD 4.3 and SunOS. One calls it TTYSIZE and one call it WINSIZE. I believe SunOS doesn't do number 2. This problem can be solved by making the xterm send the signal itself. Steve
