SERIN2 = ok, HSERIN = no!

[Demon]

That's possible, but that only explains why I got confused trying to follow his settings.

The fact remains that he was using non-inverted in SERIN, and then trying inverted in HSERIN at the end, no?

He shouldn't have to use a MAX232 with HSERIN if his GPS worked with SERIN non-inverted. Or is he on to something with HSERIN creating higher voltages than SERIN? (I have no idea about that).

EDIT: Look at SERIN in the PBP manual, that's where I got N as being inverted. His comment didn't mention a stop bit so I didn't catch on as it meaning 8N1.
