   I'm not sure and I don't remember seeing anything about it in any of the
system manuals.

  I don't think HP released one but I'll bet someone somewhere did!

  Yeap, that's one of the other names that they give.

 which was one of the CP/M file

  I have it and I have the manual. It's in the pile of the next stuff to go
to Al K to be scanned.  There used to be a website of IPC software on the
net. I don't if it's still around but I think it is.  BINGO!
<http://www.coho.org/~pete/IPC/bundled_dl.html>  That took about 3 seconds
with Google. It has the Diagnostics and Utilities along with the System
files but I don't see DataComm. You might E-mail Peter and ask him if he
has it and can post it.  You should also ask him about Kermit.
