Use this information if you are knowledgeable enough to take a shortcut when you have any problem with RealPort. Use this information also when you are talking with Digi Technical Support and they ask you to do a procedure.

Note: If this is the first time you are going through the troubleshooting process, it is recommended you go through the Main Troubleshooting Process. To get to this process, go to Symptoms: AIX.
