XENIX 386 2.3.1 Mouse Support

[Carmen Hardina]

Hi, I am trying to install my Logitech Serial Mouse under SCO XENIX 386.
It is the original three-button model connected to a true-blue IBM serial
port configured as COM1.  I ran "mkdev mouse", associated the mouse with
the multiscreens, re-linked the kernel, etc...  but when I run "usemouse"
I get the following error...

usemouse: can't open slave(errno 13)

What have I done wrong?  I think this problem has been discussed in the
group before, but for the life of me I cannot remember the solution.
And yes, I RTFM!  I thought all you had to do was run mkdev...  Any
assistance would be appreciated!  This is *very* fustrating.  :-(

The Bellcore "mgr" does not seem to understand the mouse at this point
either.  For instance, when I move the mouse up, the pointer goes racing
to the bottom of the screen and it also does not seem to recognize any
button depression on the mouse.  The program seems to lock-up for a
while, then returns to XENIX and displays the following error...

got a SIGALRM:  alarm clock
abort - core dumped

I am pretty sure that the "abort" message comes from the fact that when
"mgr" appears to lock-up, I press CTRL-\ to try and get back to XENIX.
Has anyone experienced these problems with mgr?  Aside from the Serial
Mouse, I am trying to use "mgr" with an Everex EGA card.  Has anyone
gotten "mgr" to work with EGA?  Chain did not seem to include definitions
for it in the Patches he posted...  :-(  I am not a C programmer, but
went ahead and added the following definition to the src/pc-blit/video.h file
anyway...

			#if D_EGA
			#define DEVICE		"/dev/ega"
			#define SW_MODE		SW_ENH_CG640
			#define F_WIDTH		640
			#define FB_HEIGHT	350
			#define INTERLACE	0
			#endif

I think that should put the EGA into 640x350x16 color mode.  BTW, I have
applied all 7 XENIX Patches to the Bellcore GUI and the mouse works fine
when I boot off my DOS partition.  Thanks in Advance!

P.S.  The "mgr" intro screen comes up fine.  The spinning planet with
      flying stars looks hot!  They are the best graphics that I have
      seen to date under XENIX.  Unfortunately, that is all that seems
      to work at this point...
