USART Problem Receiving Bytes

[CocaColaKid]

main:
    if RCIF = 1 then                            ' If RCIF=1 there's a new character in RCREG
        BytesIn[ByteCnt] = RCREG                ' Yes. Then store it in array
        if BytesIn[ByteCnt] = eom then OutMsg
        ByteCnt = ByteCnt + 1                   ' Increment array index pointer 
    endif
    goto Main

This code works great but how can I send the value 23? If I try it assumes each character is a byte when they are not.
