uucp on IX/370
Gunnar Stefansson
Does anyone have experience with using uucp over a modem on an IBM
machine running IX/370 under VM ?
How about setting up netnews software ? Does anyone out there recieve
news via uucp under IX/370 ?
We would very much like to hear about other peoples experiences,
both horror stories and success stories. We are considering the
possibility of having an IBM machine be a newsfeed for a number of
other machines and need to know whether this is possible and what to
expect.
Kindly reply by mail. If I get requests to do so, I'll post a
summary.

and whether anyone had tried receiving news on these machines.
Since I've been asked to post a summary of the replies, here we go
(the replies are interpreted by me -- I accept responsibility for
possible misinterpratation) :
There were only two replies, neither of whom was from a person who
had experience with IX/370. I wonder if that means that there is no
IBM machine on the net ? :-)
One reply was from an Amdahl person, who said they were running uucp
and the netnews software under UTS with no problems. No comments
about IX/370. The other reply was from a person who had worked close
to an IX/370-system. The claim was that uucp running on even a big IBM
would not work very well. This would not be the fault of the IBM or
IX/370, but the Series/1 front end and its serial interfaces. The
serial lines were claimed to be poorly designed so that the S/1 can
only support one or two 1200 baud uucp connections (even then with
lost characters).
Note that these claims are not mine. Some response would be well
appreciated, though.

About a year ago, I worked with IX/370 in trying to get uucp to work with
it. Now it is very possible that the current state of IX/370 is in better
shape now, my experiences were very similiar to the above mentioned state.
The main difference was that the loss of characters through the Series/1
was so bad, that not even one uucp connection could be maintained. It should
also be noted that the company that I was working with at the time (not CDC),
was not knowledgable (sp?) with IBM machines and it is possible that we could
have had something not quite tuned correctly. BTW, the total accumulated baud
rates for the Series/1 were well below the maximum rates given to us by IBM.
Hope this is of some help.
