    This should send out hello each 0.5 sec 9600 baud even parity instead i get 4 "Ξ" Simbols on hyper terminal, i have checked all the regesters and it seems to be ok, any body got any Suggestions??

    DEFINE OSC 20 ' Define crystal as 20Mhz

    DEFINE HSER_BAUD 9600 ; 9600 Baud
    DEFINE HSER_RCSTA 90h ' Enable serial port & continuous receive
    DEFINE HSER_TXSTA 64h ' Enable transmit, BRGH = 1
    DEFINE HSER_BITS 9
    DEFINE HSER_EVEN 1
    DEFINE HSER_CLROERR 1 ; Clear overflow automatically

    TRISA = %00011111 'set PORTA 0-5 as inputs
    TRISC = %10001111 'Set PORTC for serial coms and pins 0 - 3 as inputs
    TRISB = %00000000 'Sert PORTb as outputs and for use with the ICD2

    INTCON = 0 ;Disable interrupts

    loop:
    HSEROUT ["Hallo"]
    PAUSE 500
    goto loop

    It works here.. but i don't have the F913.. just the 917, shouldn't be the cause

    Or your Max232 circuit is wrong or you didn't set HS mode before programming your PIC.

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.

    This is not the smartest of questions but i am using mplab 8 and a ICD2 and can not find were to set the HS mode, if i understand your reply correct it is a programmer option.

    You have 2 choice, my favorite is to set the configuration bits in the code see the following
    http://www.picbasic.co.uk/forum/showthread.php?t=543

    Code:
    @        __CONFIG _HS_OSC ; minimal configuration fuse setting
    or in MPLAB, click on Configure menu, then select Configuration bit

    Not with HyperTerminal!

    Code:
    DEFINE HSER_BAUD 9600 ; 9600 Baud 
DEFINE HSER_RCSTA 90h ' Enable serial port & continuous receive
DEFINE HSER_TXSTA 64h ' Enable transmit, BRGH = 1
DEFINE HSER_BITS 9
DEFINE HSER_EVEN 1
DEFINE HSER_CLROERR 1 ; Clear overflow automatically

    I'm i allowed to not understand???? Hypercrap worked here with that setting... but... erm, i admit i've never ever dare to open the datasheet to read TXSTA settings

    Feel lazy and tired today...

    Hmmm, interesting...

    Hyperterminal doesn't have a 9-bit option.

    9-bit transmission works with 8-bit reception?
    Very interesting.

    Added: Not being sarcastic... (i know, it's a first)
    It may actually be usefull.
