NOTE
If XmLink is unable to determine a valid COM port, the Set
Communications Port for Radio dialog box appears where you can
manually select the COM port setting. Use the Communications Port
drop-down list to display the available COM ports.
The XmLink window appears providing the status of your XM service level,
radio serial number and your signal level. If you are receiving a good signal
from a satellite, you will start to see information being added in the XmLink
log. You also want to notice in the XmLink log that the Jeppesen Weather
Controller (JWC) is accepting the weather data.
6. If you are receiving weather data and JWC appears in the XmLink log, click
File > Exit in XmLink.
7. If necessary, click Yes, Exit.
