1583.0. "Zmodem file transfer program" by VTHRAX::KIP (No Dukes.) Mon Aug 08 1988 16:54

    I recently download PCOMM.ARC from PLink.  It contains "Protocomm",
    a rewrite of Comm 1.34 which uses only Zmodem for transfers.  I've
    also acquired SZ.EXE and RZ.EXE, ports of Zmodem send and receive
    programs to VMS.
    
    I've used SZ with Protocomm with success; transfers seem faster,
    although I haven't specifically timed a large transfer against,
    say Xmodem.  The recovery mode of Zmodem doesn't seem to be implemented
    though (rats, that's really why I wanted it.) Basically, the receiving
    Zmodem program is supposed to check to see if a file with the same
    name already exists; if it does, and its file size in bytes is smaller
    that the file the sender has, it is supposed to tell the sender
    to seek to the proper place in its file and append the remaining
    data to the local (receiver's) file.  Several attempts all gave
    the same result: Protocomm nuked any existing file with the same
    name, and the transfer started from the beginning.
    
    I had no success using Protocomm with RZ.EXE.  All I could get were
    timeout messages, always followed by a message apparently from VMS
    stating something to the effect that the "device" is not online or
    is not configured correctly.  I performed my usual Xmodem preliminaries
    (SET SESSION PASSALL from LAT prompt, and SET TERM/EIGHT/NOBROAD
    from VMS) but get the failure and error message.  Any suggestions?
    
    Would anyone be interested in Protocomm?  I'll upload to VTHRAX
    if so, and put SZ,RZ.EXE there also.

    I already have ProtoComm, but would love to have SZ.EXE and RZ.EXE.
    Please make these available.
1583.2VMS Zmodem progs locationVTHRAX::KIPNo Dukes.Tue Aug 09 1988 09:2610
    Ok. I put the C source, executables, and Unix manual pages in the
    following saveset:
    
    	VTHRAX::AMIGA$PUBLIC:VMSZMODEM.BCK
    
    If you happen to get recovery mode to work with SZ.EXE and ProtoComm,
    or if you get RZ.EXE to work with it, would you please post your
    methods?
    
    Thanks.

1583.4ProtoComm uploadedVTHRAX::KIPNo Dukes.Tue Aug 16 1988 10:2610
    ProtoComm is here:
    
    	VTHRAX::AMIGA$PUBLIC:PCOMM.ARC
    
    This arc file as downloaded from PLink contains the executable file
    only.  For docs, use the doc file for Comm_1.34; I believe this
    is somewhere on the Enet.  It seems as though the macro key and
    phone directory/autodial functions have been left out of ProtoComm.
    It functions as a bare bones ZMODEM file transfer program (doesn't
    emulate a VT100.
1583.5Zmodem V2.12 and ARCPNO::SANDERSBa belaganaTue Sep 13 1988 14:0232
        
        The latest version of VMS/Unix Zmodem is available at:
        
                Pno::64k_Device:[64k.sandersb.st]
        
        It is contained in the arc file RZSZ.ARC.  This file contains the
        sources, written in C, along with other sources including a
        generic Zmodem program and a header file - zmodem.h.  While these
        are VMS/Unix specific, they can be used to create machine
        specific zmodem software.
        
        The instructions to create executables are contained in sz.c and
        rz.c.  See note 216 in the AtariST notefiles for a discussion of
        X/Y/Zmodem.
        
        You will also find a VMS version of ARC (5.12 I think, copyright
        states only 1985 and 1986) - ARC.EXE
        
        These files will be available a short time (like a couple of
        weeks) due to disk quota restrictions.  If you do need to acces
        them and they are no longer there, contact me via mail and I will
        make them availabe again.
        
        Please limit you file access' to before 11:00 AM EDT, between
        3:00 PM and 4:00 PM EDT and after 7:00 PM EDT.  (We are on
        Mountain Standard Time as we don't observe daylight savings time,
        thus it puts us in the Pacfic Daylight Time zone or 3 hours later
        than Maynard.)

    	I tried the above address, but couldn't find it. Do anybody
    else has it ? I just want the executables and the documentation.
    
    Thanks.

1583.7SZ has died, out of ideasHPSRAD::BOAENTue Apr 30 1991 23:4544
I'm confused. I last used Zmodem 3-4 months ago (both RZ and SZ).
Now it doesn't work. HPSRAD has moved up a VMS Rev. in between, so I
figured it was the old run time library incompatibility. However,
I've copied SZ that has the RTL linked in and still no luck. I'm using
VT100 V2.9A which hasn't changed in the interim. also RZ STILL WORKS.

The symptoms are: amiga Zmodem exits very quickly once file transfer starts
(too quickly for me to read whatever message is being displayed). Also
an empty file with the right name is displayed in the directory I'm trying
to load into. I tried using the version of SZ with the 'vms flow control
fix' - same results also. Hints would be appreciated.


The following is my terminal setup in case something there might be
the problem:

note is that show terminal displays me as being at 2400 baud and I'm
dialing in at 1200 baud.
