* First, the canonical (but accurate) header: * I'm new to the net. * I'm sure what I'm asking has been answered before, but I couldn't find anything in comp.sources.3b1 * I'm looking for information on the following: * How can you (short of cutting and jumpering the pc board) interchange the functions of the (left)control and caps-lock keys? I believe it can be done in software, and suspect it involves /etc/ioctl.syscon, which is tersely documented in init.1m. The ioctl.syscon on my system contains the single line: d26:1805:bd:2b:0:7f:1c:8:40:4:0:0:0 (uname on my system responds: 3.5). * How can you change the shape (icon) of the mouse cursor? I have experimented with the WIOCSETMOUSE ioctl, using MSICON in the um_flags field of struct umdata. (Doc. in window.7, font.4, /usr/include/sys/window.h, /usr/include/sys/font.h). I can't get it to work. * Is there any way to modify hard disk files when booting with the diagnostic (or some other type of) floppy disk? If you mess up something (e.g. /unix, /etc/rc, /etc/ioctl.syscon), is there any way to recover, boot from an alternate kernel, etc., short of formatting the disk and re-loading all the software? * If anyone's interested (although I assume this is yesterday's news in this group), I have code that pops up an arbitrary-sized window with ksh running in it. I do not use TAM: My /etc/passwd shell is just ksh, because I want a full-size 80x24 window. But it's nice to be able to suspend and go to the other window to kill a hung process.

Get either the CAPCTL software or the second fix disk from osu-cis. CAPCTL loads in a new keyboard device driver; the second fix disk contains the 3.51m version of the kernel. Though strictly speaking the 3.51m kernel is only guaranteed to work with the 3.51 base software, people have stated here in the past that it does work with 3.5. > * How can you change the shape (icon) of the mouse cursor?

I don't remember exactly, but you can pick up "wind.cpio.Z" from osu-cis. You can set both the shape and the 'hot point' of the mouse icon with it. > * Is there any way to modify hard disk files when booting with > the diagnostic (or some other type of) floppy disk? The third disk of the Foundation Set (the "Floppy Boot Disk") is a filesystem. To use it, one boots with the second disk, which prompts you to insert the third disk. After you do so, the computer gives you a dire warning about erasing your hard disk. At this point, hit the break key, which is at that point shift-escape. You get a shell prompt, with the root filesystem being the floppy, and the hard disk mounted on /mnt. >* If anyone's interested (although I assume this is yesterday's news > in this group), I have code that pops up an arbitrary-sized window > with ksh running in it. The program "windy", on osu-cis, does this, and probably is able to set a few more things. -- Norman Yarvin yarvin-norman@cs.yale.edu "I can stand any society.
