I'm not sure if this is the proper forum for my problem, if it isn't would
someone steer me in the correct direction?

I have live stock market data coming in through an internet connection.
Then into a charting software called Tradestation 2000i. This software has
a module called Global Server that collects and saves the data. During
market hours, sometimes 10-20 times per day, Global Server will stop
collecting data even though the data is still coming in from the modem(via a
software called Dynastore...which makes the data available to the Global
Server). I can see the data coming into Dynastore, but in Global Server
it's turned off, and in the Global Server event log I can see many
consecutive error messages stating "input buffer overflow". I can restart
the data in the Global Server by clicking a choice "work offline" and then
clicking "work offline" again. The problem, besides it being a real pain,
is that I lose data...which for stock market charting is the worse thing
that can happen (to have gaps in the charts).

I'm trying to figure out what "input buffer overflow" means in order to look
for a cause and a solution. Can someone help me with this, a good specific
definition would be a great start. I'm using Win2000, is there a way to
monitor this input buffer so that I can see exactly when it is overflowing?
Is it a software (Global Server) specific problem or an Win2000 problem, or
both? I'm really flying blind right now but I need to figure this out so
I'll appreciate any ideas or information.

My computer has a P 3 1000mHz cpu, plenty of fast hard drive space, 512 mb
RAM, 56kb USR Sportster Fax modem, a telephone line that only seems to allow
28kb. I've been collecting data with this combination for 6-10 months
without this problem until 3 weeks ago. I've reinstalled the Tradestation
2000i program but nothing changed. I have also had to reinstall Win2000 in
recent months and I wonder if that could have anything to do with it. I'm
using the original Win2000, haven't updated it to sp3 yet, although in the
past it has been at sp3 level.

From your description, my guess would be a problem within the Global Server
software.

It is also possible that the problem is simply buffer overflows if the modem
is external. In this case, you can change to an internal modem or replace
the serial port with a serial port card containing a 16650 UART. This has a
larger buffer, 32 bytes vs 16 bytes of the 16650, and seems to put an end to
buffer overflows. I don't think this is the problem, based on the fact that
you said there were no problems until a few weeks ago, but it could be.
Perhaps you loaded some new software, update, or added some new peripheral
about that time and this managed to kick the problem up to the surface.
