VAX file format conversion

[Dave Mitton]

If you are importing files into VMS, you need to become familiar with the
EXCHANGE command.
(found via 
Google) 
http://h20565.www2.hpe.com/hpsc/doc/public/display?docId=emr_na-c04623262
It can do stream and carriage control conversions on various RMS fixed formats.

When we first brought up DECnet-DOS network file transfer, we had 
some "discussions" with the VMS RMS
engineers that didn't like us doing auto conversions.  This was their 
"compromise".

Oh and if you are doing serial transfers, yes, keeping the baud rate 
low is a good strategy.
I had to spend some time working on the DECnet-DOS DDCMP driver 
developing better character overrun recovery strategies. Yes, you may 
be coming in via a terminal line, but that line can hiccup from time to time.

Dave.
