Re: opencpn 4.2 will not see nmea sentences

Yet 3cp's debug window is still showing them. A second pair of backslashes preceding that would account for why the TAG blocks weren't stripped out but I can't think why that would consistently happen. Also I note that the title mentions OCPN 4.2 but the image in the first post seems to be of 4.4
Hi, Look at, gps data were pushed to frame handler unstripped.
Removing anything before $ ! as it's done in UDP could be more reliable. It's broken if there's 0 ascii character though.
It seems to be the case with Furuno, they use a non ascii header.

Just uncheck "TAG Blocks" checkbox in MPX-config.
