On SCO UNIX, switching VTs is done with Alt-F1, Alt-F2, etc., instead of with Alt-SysReq F1, etc. Is it possible to duplicate the SCO behaviour on Interactive UNIX 3.2, version 2.2? I've had a look at keyboard(7) and <sys/kd.h>, but have only been able to shuffle the VT-switching keys around; I haven't been able to reduce their number. Can anyone help? I'll summarize any responses. -- Feng Chen Voice: (604) 873-2000 feng@mtnsys.wimsey.bc.ca Fax: (604) 877-1121 ubc-cs!van-bc!mtnsys!feng

In a previous article, I asked if Interactive UNIX could be made to
switch VTs using Alt-F1, Alt-F2, etc.
By far, the most popular solution (thanks, everyone!) was a program by
Larry Campbell. It's quite short, so I enclose it below. A respondent
indicated that it runs on ISC 2.0.2 as well, and I can confirm that it
runs on ISC 2.2.
I also received a program called fixkey, by Robert Lin, which remaps
Alt-F1, etc., + some other keys, for use with Crisp. Send me email if
you'd like a copy.

The good new is that the attached program was provided by someone at Interactive and it seems to work. The bad news is that after this program is run, switching to/from a VT running X can wedge the keyboard, rendering it useless for X. Sometimes switching back and forth can fix the X server, but when I reported this bug to Interactive, they recommended that I stop using this tool and I have not had the problem since. I've stopped using VT's now that I run X, so this is not too much of a problem for me. ====== xenix_ix.c ===== #include <sys/types.h> #include <sys/at_ansi.h> #include <sys/kd.h> struct kbentry table[] = { { K_ALTTAB, 59, SPECIALKEY | (K_VTF +1) }, { K_ALTTAB, 60, SPECIALKEY | (K_VTF +2) }, { K_ALTTAB, 61, SPECIALKEY | (K_VTF +3) }, { K_ALTTAB, 62, SPECIALKEY | (K_VTF +4) }, { K_ALTTAB, 63, SPECIALKEY | (K_VTF +5) }, { K_ALTTAB, 64, SPECIALKEY | (K_VTF +6) }, { K_ALTTAB, 65, SPECIALKEY | (K_VTF +7) }, { K_ALTTAB, 66, SPECIALKEY | (K_VTF +8) }, { K_ALTTAB, 67, SPECIALKEY | (K_VTF +9) }, { K_ALTTAB, 68, SPECIALKEY | (K_VTF +0) }, }; main () { int i; for (i = 0; i < sizeof(table)/sizeof(struct kbentry); ++i) if (ioctl(0, KDSKBENT, &table[i]) == -1) { perror("xenix_in: KDSKBENT failed"); exit(1); } } -- Tan Bronson tan@Microvation.COM (or tan@bronson.UUCP) Microvation Consultants 20 Sperry Road Madison, CT 06443 Voice: (203)-421-5061 Fax: (203)-421-5292

I've always been able to fix the X server when this occured by switching back and forth when the mouse-cursor is *within* an xterm-window. Further it seems the wedged keyboard is more likely to occur when you use the ALT-F-VT-switching and the mouse-cursor is *outside* an xterm-window (though I've not been able to reproduce it 100%, there seems something more to be involved). -- Martin Weitzel, email: martin@mwtech.UUCP, voice: 49-(0)6151-6 56 83
