To change this COM number assigned, go to
Device Manager
under
Ports
and find
the device, as above. Right-click that device and select
Properties
. Click the
Port Settings
tab. Click the
Advanced
Button. You will see a box in the lower
left corner to assign a different COM port to the adapter. Please note this
procedure only works for Win ME, 2000, and XP users.
If you cannot get the serial device to communicate, make sure the settings on
the Properties tab match the ones required for your serial device. Also, under
Advanced Settings (Advanced button, above) try backing down the sliders or
disable the FIFO buffers (uncheck the box) altogether.
Finally, if you still are having communication issues, contact your serial device
manufacturer. If our adapter shows correctly in Device Manager (per above), it is
installed correctly and there is nothing further we can do. The problem is with your
serial device or its software settings.
