5. Troubleshooting
5.1. Port unavailable
If the installation of the USB Serial Adapter has been completed
but the port is unavailable to applications, follow the instructions
below to diagnose the problem:
1. Check the LEDs on the USB Serial Adapter.
• If the red light is on steady, skip to the next section.
• If there are no lights on, check to make sure the device
has been properly plugged in.
• If the center, green LED is blinking steadily, the device
has not been configured properly. This can happen if
the wrong drivers have been installed for your operating
system. If the wrong drivers have been installed or if you
are not sure, follow the instructions in section 3.3,
Uninstalling the USB Serial Adapter Drivers and reinstall
the software.
2. Check to make sure no other applications are using the
COM port.
3. If you have enabled DOS Box support, make sure that no
other applications are using the Windows ® name for the
COM port or the DOS name for the COM port (see section
4.4 Using the USB Serial Adapter with DOS Applications).
