[comp.os.minix] Strange behavior with virtual console

boehme@leah.Albany.Edu (Eric M. Boehm) (06/27/90)

I am having some problems with the virtual console. Sometimes, I get
colons ( : ) replaced by nulls (^@). I can tell because if I redirect
output to a file, the missing characters appears as a ^@ when I edit the
file. Related to this, if I use pdtar to extract tar files, sometimes
characters in the extracted files are changed from colons to nulls and
the files are corrupted. The tar for minix doesn't seem to have this
problem.

I am also having problems with elle. When TERM=minix-vcam, elle
complains that terminal lacks cursor addressing or clear the screen. The
termcap includes both of these. if TERM=minix, it works okay. The only
difference between minix and the rest (minix-vc, minix-am, minix-vcam)
are additional capabilities. Has anyone else had this problem?

I currently have four virutal consoles enabled. When I run the ps for
the virtual console, t1 through t3 show up in the display, but t4 and
t65 show up as a '?'. Even after rebooting, this persists.

Any suggestions or explanations would be appreciated. All the crcs
checked before and after making the changes.

There was a small change to ps between 1.5.6 and 1.5.10 to handle ttys with
large minor numbers. A couple of login accounting programs, such as `last'
are still confused by large minor numbers.
