Hi Bob,
?
I had a similar problem the other week when I tried to use a USB to Serial Adapter (for NCE Power Pro 5) with JMRI 5.6 on a Windows 11 laptop.
?
I solved the problem by editing (in Notepad++) the profile.xml file for JMRI and removing a section relating to the connection:
?
I looked for the section named </connections and then found a section that started <connection> that contained the connection for the NCE via serial interface.
?
I removed that entire section from <connection to </connection>? ?hopefully someone who knows more about JMRI can correct me if I wrote that down incorrectly or I'm not using the best solution or I was just lucky.
?
I then saved the profile.xml back where I found it, restarted JMRI Panel Pro and then it booted up correctly instead of hanging.
?
Regards
?
Nick
