Asynchronous baud rates on a 12F683 (serin / serout)

Greetings all:

Is there a maximum baud rate for serin/serout on the 12F683? I'm trying to port code from another device at T9600 and can't get the 12F683 to pic up the data on serin. I'm thinking maybe this chip is too slow?

Thanks for any and all ideas . . .
