    Well, I can't offer any suggestions for fixing what you have, other than CTRL-A/DEL.

    Give this a try with HyperTerminal or equivalent @ 19200 baud.
    I'm assuming it's a 16F877.
    Code:
    <font color="#008000"><b>CLEAR                              </b></font><font color="#0000FF"><b><i>' Clear all User RAM

    Hi, Darrel

    Could you explain the second Item in the list: "[2J"

    and further

    Code:
    DisplayCounters:    
    HSEROUT [27,"[H"]      ' home cursor (ANSI)
    this one : "[H" ???

    May be simple for you, but unknown for me !!!

    BTW: Thanks for the example ... as I just begin serial comms use to pass parameters to and from my PICs and the PC. ( PC is an horrible black box ... I never look into, as you've understood : LOL )

    Alain, this is the ANSI escape codes for the terminals. It does exactly what Darrel remarked, Home position in the terminal window.

    Question

    Hi, Ioannis

    Thanks, but what I do not understand is ... both place cursor @ home position ...

    further question will be :

    is there any table or link to these codes ??? ...

    Now I got what you meant Alain. But then you caught me on the turn. I was going to post the link for the Escape codes.

    I tried them few times, but my terminal was getting confused often. I had to restart it to make it work properly.

    Talking OK. Here I am come!

    Man. You are the best! I tried with 16F870 and works perfect.
    Now I must write the counters data on internal eprom and send via RS485 to "master" computer on Request. I think I'll be able to in this. For now, thank you very,very much.

    PS
    I hope you will help me again if it is needed.
    It's nice to have your own guru(mentor)
