In our institute we have an IBM AT 6 MHz and an IBM proprinter.
I get always the error:  printer out of paper - printer error.
I have tried to force a) the monochrome adress b) the color adress
(we have a coulor monitor)  - but same results.
On other machines (and other printers) the driver works.

But please send no update vs. 1.3b but vs. 1.3a (or 1.2).
Many people can so skip a step and spare a lot of work.
(Updating kernel, lib and commands requires about 30 hours on an AT)

>Discussion on the subject of cdiff/patch vs diff/fix should be posted
I like diff/fix. The cdiffs are MUCH to big. The context is not necessary
because many people don't look at the diff's. People with own fixes should
have official versions too.

I have written a shell script to check the sums:
(it uses a sum file produced by suns:
<sum>	<block> <name>
)

sed 's/^X//' >cksum <<EOF
X#verify the checksums given in a file $1
X
Xif test $# -ne 1
Xthen echo usage: $0 sumfile
Xexit
Xfi
Xcount=1
Xfile=$1
Xset `wc -l $file`
Xlen=$1
X
Xwhile test $count -le $len
Xdo
Xset `head -$count $file |tail -1`
X#sort information in checkfile line
Xname=$3
Xsum=$1
Xblock=$2
X#run sum
Xset `sum $name`
Xif test $sum -ne $1
Xthen echo sum von $name falsch
Xelse echo -n $name OK '	 '
Xfi
Xif test $block  -ne `expr \\( $2 + 1 \\)  / 2`
Xthen echo block von $name falsch
Xelse echo $name OK
Xfi
Xcount=`expr $count + 1`
Xdone
EOF
if test `wc -c cksum` -ne 498
then echo Error in cksum
fi

The length of ls.c, cp.c, dosread.c and df.c of 1.3a
are are not the same as posted in #7 (<768@ast.cs.vu.nl>).

There were posted two chgrp.c this year but none with the
lenth specified in #7.
No length agreement further exists for compress.c ed.c file.c lorder.c.
commands/tty.c   and diskcheck.c i have never seen.

My wishes for christmas: Virtual terminals for minix (like xenix)
                         or Berkeley enhancements for process control
