Hi,=0AI'm trying to find some info on how to do basic programming on mac se=
rial port. =0AI came up with the followin algorithm=0Aset pin1 high=0A|=0Ac=
heck if pin2 is high=0A         |=0A        / \ =0AHigh     Low -> go to ch=
eck if pin2 is high=0A|=0Awrite character to a file -> go to check if pin2 =
is high=0A=0Apin1 and pin2 are connected to a shaft sensor which gives n am=
ount of short circuits in 1 revolution=0A=0Apin1=0A  |=0A =3D=3D shaft sens=
or=0A  |=0Apin2=0A=0Auname (just in case)=0A[wally@macppc ~]$ uname -a=0ANe=
