Has anyone ever tried to transmit/receive at different
baudrates...basically changing baudrates between pieces of data?

I'm having problems and basically have narrowed it down to the receive
module on the PIC.  I'm using a 16c74a which has a double buffer in the
receive module.

Does anyone know what happens to the receive module when baud rates are
changed (i.e. changing the SPBRG).

Thanks.
