Code:
TRISB = %10000000   'use TRISB to specify which pin is (1 = input) and which (0 = output)  (RB7 PORTB.7 is the RX input pin of the EUART, the rest are output)
TRISC = %10000000   'use TRISC to specify which pin is (1 = input) and which (0 = output)  (RC7 PORTC.7 is the RX input pin of the EUART, the rest are output)
                    'in PORTC the RC3 attached is an LED.
setting the tris incorrectly will stop the eusarts from working


from data sheet

Setting the TXEN bit of the TXSTAx register enables thetransmitter circuitry of the EUSART. Clearing the SYNC
bit of the TXSTAx register configures the EUSART for
asynchronous operation. Setting the SPEN bit of the
RCSTAx register enables the EUSART and
automatically configures the TXx/CKx I/O pin as an
output. If the TXx/CKx pin is shared with an analog
peripheral the analog I/O function must be disabled by
clearing the corresponding ANSEL bit.
