I'm not sure you'll get the hardware USART to work at 115200 bps, but you can work with this data rate using DEBUG & DEBUGIN.

I've tested this on a 16F876A with max232/PC connection.
Code:
DEFINE OSC 20
DEFINE DEBUG_REG PORTC
DEFINE DEBUG_BIT 6     ' USART TX pin
DEFINE DEBUG_MODE 0 ' 0 = true for max232 inversion

DEFINE DEBUGIN_REG PORTC
DEFINE DEBUGIN_BIT 7  ' USART RX pin
DEFINE DEBUGIN_MODE 0

DEFINE DEBUG_BAUD 115200

X VAR BYTE
Y VAR BYTE
Z VAR BYTE

MAIN:
    DEBUGIN [WAIT("A"),X,Y,Z]
    DEBUG X,Y,Z,13,10
    GOTO MAIN
    
    END
