Error upon quitting the TUI, Missing Port0 entry

[SeptenJDT]

Upon quitting the TUI I get following error.

This is solved by two modifications in SaveConfiguration.py
line 59
#config.add_section(section_name)
to
if not config.has_section(section_name):
config.add_section(section_name)

line 129 add
if not save_config_file.has_section(section_name):
save_config_file.add_section(section_name)
