3576.0. "Upload Problem with Zmodem" by AKOV11::SMITH (Reality, just a visible imagination?) Mon Mar 12 1990 10:21

I'm having a problem uploading files from Amy to VAX using Zmodem.  I do
so infrequently (until now) so it hasn't been a concern.

However, I (regularly) download files using (VAX) SZ V2.12, VLTjr V4.428,
and XPRZmodem V2.0 without difficulty.  I can also successfully upload to
the VAX using XMODEM and VLTjr.  So what gives?  

The only thing I can think of is my RZ (V2.03) copy is bad, but I tried 2 
different copies, or I'm doing something wrong.  Can anyone steer me straight?

Here's what I doing and the results...

1. Login to the VAX using VLTjr

2. On the VAX type:	$ RZ

3. On VLTjr select pulldown SENDFILE (with external protocall of course)

4. On VLTjr file requestor select file and punch OK.

5. File transfer box opens and transfer continues without error until complete.

6. On the VAX I get my prompt back and I list the ZOO file I just transfered
   and it's corrupt!

7. If I transfer the same file now with XMODEM everything works and the ZOO 
   file is fine.  I use VAX XMODEM and VLTjr XMODEM.


Any Suggestions?

3576.1Hold it, that zoo may not be corrupt...CGOFS::CADAMSClint Adams - Calgary, CanadaMon Mar 12 1990 12:128
    Hi Ed, hows it goin'.
    
    Believe it or not you probably did upload OK, the problem is that VMS
    made a fixed 512 file for you when you used RZ on the VAX side and VMS
    Zoo hates it. Do a "CVTARC u" to change the zoo file to stream or use
    VMSSweep (yuk) to read it. Works for me..

    Ditto RE: .1 
    
    Your file is okay. A VAX isn't an Amiga. Likewise if you download
    a .ZOO file from the VAX that was ZOO'ed on the VAX, you won't be
    able to deZOO it on the Amiga. In other words, if you can list the
    ZOO file on the VAX, chances are you won't be able to deZOO it on
    your Amiga.
3576.3Zmodem = dont' worry about file format...CGOFS::CADAMSClint Adams - Calgary, CanadaMon Mar 12 1990 13:298
    re: .2
    
    I have found that if I use Zmodem for downloading to the Amiga from the
    Vax that I don't have to worry whether the file is fixed or stream. The
    file is always OK at the Amiga end. As has been stated many, many, many
    times in the past, the above is not the case for Kermit and Xmodem.

3576.4TALLIS::MCAFEESteve McAfeeMon Mar 12 1990 16:165
    I agree.  ZMODEM works for me regardless of the file format and
    regardless of the direction.  As noted earlier, you will need
    cvtarc to change between formats on the VAX.

3576.5ENOVAX::BARRETTOf Optical Mice and Men...Mon Mar 12 1990 16:2912
    What are most people using for a communication program for an upload?
    SMOKEY doesn't have ZMODEM, and I have a problem when using
    ONLINE! or ONLINE_PLATINUM!:
    
    	If I start the sender first (the Amiga), the terminal screen is no
    	longer active for me to enter my VMS transmit command.
    
    	If I start the transmitter first, the program automatically detects
    	this and tries to receive the file - but with an illegal VMS
    	filename -- and dies.
    
    Out of the others (VLT, JRCOMM, etc), which works best for VMS uploads?
3576.6I thought EVERBODY was already using VLT...;^)CGOFS::CADAMSClint Adams - Calgary, CanadaMon Mar 12 1990 15:326
    
    VLT(jr) is by far the best all around terminal emulator, it has terrific
    file transfer support, a great 132 font and a review buffer.
    
    	Regards...   Clint

    I'd use it too if it did vt220 emulation.  FOGGY seems to work
    fine for me using KERMIT.

3576.8Fixed! RZ.EXE 155 blocks was bad.AKOV11::SMITHReality, just a visible imagination?Mon Mar 12 1990 22:4533
    Re .1
    
    Hi Clint, 
    
    Hows things in CGO.  On your suggestion I tried a little experment
    using the AMGIF.ZOO file.  Doing a DIR/FULL on the VAX showed that this
    file was STREAM_LF format, 31 blocks long.  A "ZOO l AMGIF" on the VAX 
    worked fine. I "SZ" the file to Amy, listed and unpacked ok.  I then
    repacked the same files into AMGIF1.ZOO.  I then "RZ"ed it back to the
    VAX.  A DIR/FULL indicated the file was still STREAM_LF but was now
    62 blocks.  Trying to list or deZOO the file indicated it was corrupt.
    
    Well I'm not one to give up (and just use XMODEM), so I had another
    look at the SZ/RZ versions.  I was sure I tried them all!  Some time 
    back I had updated them with what I believed to be a newer version.  
    It turns out that the older version (by date) works fine.  The bottom 
    line is there appears to be two versions of SZ/RZ floating around.  
    Doing a "RZ -h" and a "SZ -h" on both versions indicate they are the 
    same version but the file sizes are different. ie:
    
    SZ.EXE	170 blocks	V2.12		Works ok
    SZ.EXE	157 blocks	V2.12		Works ok
    
    RZ.EXE	155 blocks	V2.03		*FAILS*
    RZ.EXE	143 blocks	V2.03		Works ok
    
    So beware... The larger file size EXE's (also newer by date) appear to be
    the source of the problem.  If you have had problems with ZMODEM, check
    this out.
    
    Thanks for all the replys,

3576.9CLO::COBURNGrowing older, but not up...Tue Mar 13 1990 07:5214
    Don't be too positive. I have V3.01 of RZ that I built from source and
    it still exhibits the symptoms that you describe. 
    
    It seems to occur when the protocol detects an error and has to
    retransmit a block - it seems to retransmit every block though.
    
    I haven't used RZ for uploads because the YMODEM stuff is just as fast
    (for me anyway) and I don't (or haven't yet) upload much stuff.
    
    Let us know if your version continues to work OK. Everytime I try to
    use ZOO in ASHELL while uploading I induce a comm error on the upload.
    (All this using VLTjr).

3576.10Success = 2 for 2 attempts sofarAKOV11::SMITHReality, just a visible imagination?Tue Mar 13 1990 07:256
    I let you know if it fails.  Last nite I tried 4 uploads, 2 with each
    version.  The larger file size RZ failed each time and the other
    worked.  I was performing no other work on Amy at the time.

    Things are just peachy here, Ed.
    
    The version of RZ we run around here is 3.01 (Chuck Forsberg and a date
    of 5-25-89 listed after a RZ -h), this is the same executable Wayne
    uses to upload Fish disks to our system with astounding reliability.
    
    I'll make it and it's mate SZ (version 3.03) available in
    CGOU01::amiga:[new]. These are both compiled ands linked under the VMS
    V5.

    I've not had any RZ problems and I'm using version 2.02.

    Is it possible that the version you have is appending the files?
