Serial1 - Atmega2560

hi guys,

i have strange problem.
i made class encapsulate adafruit_gps (https://github.com/adafruit/adafruit-gps-library/blob/master/adafruit_gps.cpp) library abstract other parts of code possible change of gps.

so make call class, creates object using class of adafruit_gps serial1.
until ok, works. problem happens when turn off board , turn on again.
the code considering serial1 sw, not hw. (line 252-269 of library.)

i removed parts of code. maybe have deleted funcção or other unintentionally. if feel lack of something, let me know.

but said problem happening when unplug board , again reconnect. never saw , have not found on internet ...

i thank can help.

thank

sorry poor english ...

what sort of arduino have ?

on mega use serial1.

for other kind,  use software serial.
