- Hello world!
-
- I got VMS (5.4 & 5.5) to transfer binary files over a modem line. But on the
- receiving part, VMS changes the record format to an inacceptable one.
- A disk save set formerly
- Record format: Fixed length 32256 byte records
- Record attributes: None
- is converted to
- Record format: Stream_LF
- Record attributes: Carriage return carriage control
- All else is the same.
-
- This effect yields by both ZMODEM and
- two versions of KERMIT. Unfortunately I couldn't get the
- BLISS-Version running, there is a BLISS-Compiler missing
- and the uuencoded Version of the .EXE-file was corrupt.
- Nevertheless, ZMODEM is said to get better throughput than
- Kermit (actually, I got about 150 CPS using ZMODEM and 60 CPS
- using Kermit).
-
- DIFF as well as CONVERT complain they
- can't handle the transferred files giving a RMS error message.
- A self-written "diff", comparing both
- files byte-by-byte using open(2) and read(2) tells me, both files
- are exactly the same. BACKUP doesn't accept the transferred file as
- a save set.
-
- Then I found a DCL-Prozedure (it's called KERMIT_VMSBACKUP_RESTORER.COM or
- something similar) on NRLVAX.NRL.ARMY.MIL which should
- correct this problem, i.e. save set's should be readable after a
- transfer. Still, they are not. This is the log of it's run given
- 32528, which is the default /BLOCK_SIZE of BACKUP, as the third parameter:
-
- BLOCK_SIZE = "32528"
-
- Ready to process SAVE_SET BACK.SET
- SAVE_SET BACK.SET PROCESSING BEGINNING

- %COPY-W-INCOMPAT, SYS$USER:[SCHMIDTAT.TMP]BACK_NEU.SET;1991 (input) and SYS$USER

- The most curious thing is that VMS _is_ able to run an
- .EXE-file, which is of
- Record format: Stream_LF
- Record attributes: Carriage return carriage control
- But I won't rely on this, who knows, how the next versions of
- VMS will handle this. Furthermore, other programs and utilities
- presumably can't handle converted files (RALLY? RDB?).
-
- My questions:
- 1. How do I get ZMODEM (or Kermit, if this is, what you can
- answer) to _not_ converting the file type? Is such a version
- available somewhere on the InterNet?
- 2. How do I restore the record type of the
- received file? CREATE/FDL doesn't work, due to a RMS-error
- (something about to big record or buffer size)
- I already tried writing a quick hack using open(2) and
- write(2), which opens an existing target file of correct
- record type (just like the mentioned DCL-Procedure did),
- but write(2) seems to be interpreted by VMS
- somehow and the same error as using DIFF or CONVERT showed
- up.
-
- Please email answers directly to me, as I am reading this group
- only frequently.

- Thanks for your help,
