If they refuse to, then use the sniffer approach that I suggested in the
last message.

Correct...  my thought was that the vendor actually wants to receive x'0b'
and x'0d' and x'0a' rather than whatever you get when you translate an
EBCDIC x'0b' to ASCII.

Well, actually in the code you showed me, you had x'0d25' (not x'0d0a')
though, after the EBCDIC to ASCII translation, it should become x'0d0a'.
But, I don't see the point of translating them...  Why use extra CPU
cycles translating x'0d25' to x'0d0a' when you can just send x'0d0a' in
the first place?

And, I have no idea (without looking, anyway) what x'0b' gets translated
to when it becomes ASCII.   I assumed that the vendor actually wanted
x'0b', rather than whatever it translates to.

Yeah, that's fine.  I just used callp instead of eval x = send (blah blah)
because I was lazy when I replied to you.   You should, of course, be
checking the return values not ignoring them like I did.

I was just trying to show you the technique of translating SOME of the
data to ASCII without translating it all..

You bet.
