Yeah. HP was actually the other company that actually seemed to

One could only wish companies had. Everything would have been soo
much easier in that case. Now almost everyone is confused when it
comes to serial communication, and it's not because it actually is
difficult, but people have just become so confused because they
think it works one way just because the equipment they have do it
that way, and when coming to any other equipment, nothing works the
same way they are used to.
Well, you've got to admit that things would've been a whole lot
easier if it weren't for the whole DTE/DCE fiasco.

In general, when talking about DEC equipment, the
answer to that
question is *always* no, for the simple fact that DEC didn't do
hardware flow control. Hardware flow control is actually against
the RS-232 spec, and DEC didn't abuse standards (unlike most
other companies).
This reminds me of a comment I made about the HP82164 (HPIL to
RS232 interface). That thing follows the RS232 standard to the
letter (for example, it correctly handles the cotnrol lines in
half duplex mode). It's just a pity that nobody else does :-).
Getting it to work with some RS232 devices is 'interesting'..
