From what I'm reading, having a newline (CRLF) at the end of an NMEA sentence is a requirement. Without it, some software and/or library modules/packages don't properly read/parse the NMEA sentences coming from the current version of gpsfeed+, as they are relying on the newline as a NMEA sentence delimiter. As such, I request adding an option to have gpsfeed+ put a newline at the end of each NMEA sentence, controllable through a checkbox on the Connection tab within the gpsfeed+ Configuration dialog. For reference, I'v attached an updated gpsfeed+.tcl script that I modified to add the newline for TCP, UDP and Serial connections, as well as to restore buffering on UDP connections, which is enabled for TCP and Serial connections. In kind, I've restored the flush command after sending UDP data. See the post I just made under the Open Discussion forum, awaiting moderator approval, which goes into more detail on this.l
