This may be an old subject to some, news to others. I received the DTN 8000
receiver today and it was accompanied with a Chameleon software user guide.
Appendix C is titled "Solutions for Com Port Errors". Here are a few quotes
from it, "Users who have migrated from Windows95 to Windows98 have reported
that while there were no or few errors in Windows 95, errors increased
sharply in Windows 98. A high number of CRC or overrun errors (more than 2
or 3 per hour) may result in lost or erroneous data. " Their conclusion was
that W95 or NT were better choices than W98. I suppose W2000 would also be
included, but it wasn't available when the book was written in 1999. This
is pretty much what traders have experienced. Some have changed data feeds.
Some have tried the TurboExpress card.
The Appendix C recommended solutions are:
1.In the System Device Manager drop the FIFO recv and Xmit port settings to
the next to lowest setting.
2. In the Advanced Graphics Settings move the Hardware acceleration slider
to the second lowest setting. Restart computer to make the changes
effective.
Another suggested alternative for Win98 users is to use a USB to serial
converter. This along with an installation disk makes the USB port look like
a COM port. "In testing, there were zero errors from day to day, with only
an occasional CRC error over a week's time using the converter. The
converter emulates a COM port but is actually a USB device, using no IRQ or
other resources. You do not have to open the computer case to install the
converter. You insert the installation disk that ocmes with the converter
in your flopppy drive, then plug the USB Type A conector into an available
USB port on your computer. Windows98 automatically displays a message box
"Unknown Device Found." Follow the instruction tat come with the converter
to install the device drivers from the floppy disk to your computer's hard
drive. Typically the converter installs as the next available unassigned
COM port. When installation is finished you can check Device Manager to
confirm the new COM port assignment.
The next suggestion was the use of the TurboExpress card which many are now
familiar with.
I would like to know if anyone on these lists has tried the USB to serial
converter. If so which make and model was used? What are the baud
limitations?
Thanks,
BobR
