Hmmm.

1) I have only been able to reproduce this by
manually adding a DBPort=0 line in mysql.txt.
If there is no DBPort= line, or if it has no value,
TestDBconnection() will have port.length() == 0,
and there is no telnet (port check).

2) I cannot see why DBPort=0 would be in the file,
because the settings UI doesn't write a DBPort line
if the value entered is blank or 0?


But, I have checked in [14224] which
should skip the check in your case?
