When I try to connect to another program, and the user has not logged in, it starts printing these messages:
I know how to get the ones highlighted in red, using a try-catch routine. But how can I search for the ones in black? The ones that say "failed to connect using..."?
Is there a routine I can use to raise a flag when this events are registered on the command window of Matlab?
Thanks for your help!

These links may help to get the exception message displayed :
  1. There is a function "getReport" which can be used to get the message displayed for an exception. Here's the link to the doc : https://www.mathworks.com/help/matlab/ref/mexception.getreport.html
  2. You can also log the command window text to a file using "diary" command. Here's the link to the doc : https://www.mathworks.com/help/matlab/ref/diary.html
Hope this helps.

Try using the getReport function. You can put the code in try catch blocks and store the exception messages in variables.
A small example could be:
try
surf
catch exception
errorMsg = getReport(exception)
end
Here, errorMsg will have the error text stored.
