Socket Mobile Cordless Serial Adapter - Manual (Page 42)

Appendix D Troubleshooting
SYMPTOM:
The Configuration Utility is not working properly
(e.g., I cannot read the settings from the CSA) and/or I get an
error message that says “Unable to open the COM port.”
POSSIBLE REASONS SOLUTION
The CSA is not attached properly to
your computer. Properly insert the CSA, pushing it into
your computer’s serial port as far as it will
go.
The CSA does not have power. The
LED is not blinking. Use the AC adapter to connect the CSA to
an electrical outlet.
The CSA currently is configured with
automatic connections and DTR
disabled, and the remote device is
within range. Thus, you are currently
connected to the remote device. Remove the remote target from range.
ActiveSync has control of the port
where the CSA is attached. In the ActiveSync connection settings,
make sure a serial cable connection is not
allowed at the COM port where you
attached the CSA.
Your computer is already connected to
another device using the same COM
port that the CSA is trying to access. Disable the conflicting connection.
SYMPTOM:
The CSA is not communicating properly with my
third party software.
POSSIBLE REASONS SOLUTION
You configured the CSA and/or the
third party software incorrectly. Make sure the CSA and third party
software are set for the same baud rate and
other settings.
You are using auto-detect and Plug
and Play functions. Auto-detect and Plug and Play functions
do not work reliably with Bluetooth. Make
sure you manually enter the baud rate and
other settings to match those of your local
host device’s serial port.
Various possible reasons, such as
incompatible hardware. If your hardware responds to standard AT
commands, set up a test connection with
Windows Hyper Terminal using the CSA
COM port as the connecting modem.
