[comp.sys.apple] A solution to the Kermit unpacking problem

numccann@PLAINS.NODAK.EDU ("Lester I. McCann") (01/12/89)

Thanks to Murph Sewall, I managed to get Kermit 3.85 installed last night, 
without so much as a single disk grind.  Apparently the secret is to use 
Kermit on a DOS 3.3 disk to download the two files (APP385.1 and APP385.2)
directly to a DOS 3.3 disk, and then install them.  I had been downloading
with a ProDOS Kermit and using CONVERT from the old ProDOS User's Disk to
transfer the files to DOS 3.3.  Note that the Kermit executable file runs on
either ProDOS or DOS; there really aren't two different versions.

Moral: even if you use Kermit under ProDOS, save the most recent DOS 3.3
disk you had to make to EXEC the EZ Install and then use that to download
the next version when it comes along.

The EZ Install works only under DOS 3.3 (sometimes it's amazing that it
works at all, but if you are *especially* nice, it WILL work :-).  Some
Apples (with only 48K -- make nice "dumb terminals" even if they can't
run the latest gee whiz software) and old Franklin's (which don't have
a patched ProDOS around) wouldn't be able to make a new version if Kermit's
EZ Install only worked under ProDOS.

I got another kermit from columbia, and it's archived
with the last one.  I may delete the other version 
sometime, but it's in three parts, whereas the one
I just got was only in two.

I think I'm jumping on the "Primos sucks" bandwagon.

I suspect Apple's CONVERT copies files from AS-IS (all 8 bits) from one
operating system format to the other without regard for file type.
NORMALLY, ProDOS 'TXT' files have the 8th bit off (zero, down, clear,
whatever), while DOS 3.3 'T' files have the bit set.  MOST (not all) DOS 3.3
software (word processors, whatever) don't care whether the 8th bit is
set or not (after all it's SUPPOSED to be a 7-bit file).  I have seen
some *strange* interpretations of the carriage return character when the
8th bit is the opposite of what's expected, but that's unusual.

I haven't done any real analysis of the EZ Install, but I suspect it uses
some of those cute "when is an EXEC file not an EXEC file" tricks described
in this month's Call-A.P.P.L.E.  The 8th bit seems to matter.

Text files downloaded with XModem (whether to ProDOS *or* DOS 3.3)
are unlikely to have the 8th bit set (the 8th bit off is the standard
used by MS-DOS, Commodore, Tandy, whatever) unless the commware has a
special option for setting the bit (some word processors will let you
"twiddle the bit" just by loading the file and saving it -- not all
that easy to do with a 55K file on an Apple :-)

Kermit-65 KNOWS a text file isn't a binary and sets the bit as appropriate
for the operating system (so does Copy II+ apparently -- Copy II+ might
even set the bit for a copy downloaded by XModem just by copying the
file from one disk to another).
