Poderosa is not able to save serial port settings short cut to .gts file.
The new .gts file gets created but it is completely empty. An exception gets thrown. See attached error.log.
The entry in most recent connections from "File" menu item gets created correctly (named "COM4" in my case) and opens fine.
