How fast is that chip? Is doing a multiplexing? The 16F688 is 8Mhz , the serial is set to 9600 baud , when i have use it i don't have loose any chars i pressed on the KB. You will see in the source that the PIC only wait and translate the keyboard scan-code. I don't have use interrupt , it's a pure bit banging system because every KB don't send the bits at the same speed. And about how fast it was , you can consider that it was exactly the speed of the KB Cheers. Theory is when we know everything but nothing work ... Practice is when everything work but no one know why ;)
