I doubt that a PCI interface to a serial port would make any difference over
an ISA serial port. A standard 8MHz ISA bus speed is plenty for serial
communications. Even at 460800bps you're no where near maxing out the
bandwidth.

Richard, it's great to hear from you one actually use the setup and
get
feedback from the horse's mouth. Since I'm using DTN along with many
others
with success I wonder what is the difference. Somehow I sense that
the issue
might be ISA vs. PCI? But then how come things seem to work with
DTN? I've
done design work on mainframes in the late 70's and the 80's and
without
actually running a diagnostic to determine the max speed that the
data can
be moved from the card through the bus (ISA or PCI) to memory I'm in
the
dark. Is there anyone on this list that has a grasp on this?

Dear Ron, Attila, & Group,
I've been using QFeed + DynaStore + TS4 off and on for the past
month or two
and have been having all the problems that you have discussed, chart
slowing, chart stopping, crashing, etc.
Several weeks ago, I heard about the Pacific CommWare TurboExpress
920 Port
card and, after perusing their website
http://www.pacificcommware.com , I
called them (800 960 6444) and spoke with their technical
representative,
whom I recall was named Travis (?). I told him my problems with the
connection between DynaStore and TS4 and asked him if he thought his
TurboExpress card might help. He said "No" but offered to refund
its
purchase price if I bought one, so I could test it and see if it
might
help. I did buy one ($80) and have used a for the past week or two.
I
cannot detect any difference in the performance of TS4 as a result
of my
installation of the TurboExpress card.
I do hope that I am wrong about this, and I do invite you and anyone
else to
see if the installation of a TurboExpress card or any other
after-market
"fix" could improve the performance and reliability of TS4 to chart
data
received from the DynaStore program.
Parenthetically, the TurboExpress card is an ISA-type card; Pacfic
Comm Ware
does not build it in a PCI-type configuration, and their
representatives
tell me that they have no intention of doing so. I would be
interested in
obtaining a data-buffering serial card, like the TurboExpress (or
the
defunct Telcor T-Port), made in a PCI-configuration. If any of you
are
aware of such a card, I would appreciate your telling me its
manufacturer
and their contact points, eg website, phone number, etc.
Sincerely,
Richard
