I've used the MAX3110 before without any problems. Just quickly looking at the parts, the 3110 seems to be a 3100 with built in level converters. The pic I used had an external interrupt, so I just wired the 3110's INT line to INT0 on the PIC. I configured the 3110 to throw an interrupt whenever there was new data in the fifo and wrote an ISR that transfered one byte from the 3110 to the pic. Seemed to work fine for me.
