Re: slow queries over tcp/ip

Yes.  I do believe that this would be the case.   Are you getting at
something?  Why would this matter?  Again, ALL 5250 terminals are OK under
ALL circumstances.  ALL PC's communicating over tcp/ip are affected by this
slowdown.

If there is anyone out there using tcp/ip?  Do you generally see improved
speeds vs twinax?

Thanks,
Keith
