Roger, what have you configured the serial port to. Reading the manual the value for MODE if using 9600 baud rate, with the normal 8 bit, no parity, 1 stop bit the value is 84, but you have bdrate (same as mode in the manual) set to 49236....

from the manual - SERIN2

Some examples of Mode are: Mode = 84 (9600 baud, no parity, true)
