HI Tony,
i used to send midi messages with the serout2 command at 31250 only with 16 and 20 mhz xtals and it works!

If you look at the datasheet of the 16f675 everything is revealed to you!

I think that ANSEL %00110011 sets the ad conversion clock to FRC and gp0 gp1 to ad inputs.

ADCON0 is the A/D CONTROL REGISTER, you use it if you want to set the conversion less automated.

I disable the comparators only for precaution!

bye
