Appendix A: PC to BASIC Stamp Communication Trouble-Shooting · Page 303
√ If you are using a serial port (no USB to serial adaptor), make a note of the COM
ports listed. If one or more of these COM ports do not appear in your BASIC
Stamp Editor's list, make a note of the numbers for each COM port that doesn't
appear in the list now.
√ If you are using an FTDI USB to Serial adaptor, look for the COM port that
reads FTDI USB to Serial COM…
√ Repeat the
Run → Identify test.
√ Click the
Edit Ports List button and add the missing COM port numbers.
√ Repeat the
Run → Identify test again, this time, the Identification window should
"find" your BASIC Stamp 2.
Still no BASIC Stamp Detected?
√ If you have more than one COM port, try connecting your Board of Education or
BASIC Stamp HomeWork Board to a different COM port and see if
Run →
Identify works then.
√ If you have a second computer, try it on the different computer.
If you get the error message “No BASIC Stamp Found” but the
Run → Identify test shows
a “Yes” in both columns for one of the COM ports, you may need to change a setting to
your FIFO Buffers. This happens occasionally with Microsoft Windows® 98 and XP
users. Make a note of the COM port with the “Yes” messages, and try this:
Windows
® 98:
√ Click on your computer desktop’s
Start button.
√ Select
Settings→ Control Panel → System → Device Manager → Ports (COM & LPT).
√ Select the COM port that was noted by the Run → Identify test.
√ Select
Properties → Port Settings → Advanced.
√ Uncheck the box labeled “Use FIFO Buffers” then click
OK.
√ Click
OK as needed to close each window and return to the BASIC Stamp Editor.
√ Try downloading a program once more.
Windows
® 2000:
√ Click on your computer desktop’s
Start button.
√ Select
Settings → Control Panel → System → Hardware → Device Manager → Ports
(COM & LPT).
