Hi

Iam trying to read the time of the gps "Garmin 12", to my pc through SX. I wrote the following program, but with no results. Please, can any body help me to do the task?

Thank you in advanced

    The logic looks okay.

    If you are using a 50MHz resonator I think you'll need to use OSCHS2 on the device line instead of OSCXT2.
    Is the PC expecting just 3 binary bytes ? What software are you using to receive on the PC ?

    Okay then you don't need to convert the data.
    Just receive it and resend it.

    Try this...

    When I used this, not the time that will be displayed on the monitor, but another things.
    Iam also using: max 232 between the SX and the gps and pc
    Is this is a time problem?

    You probably will have to use N4800 for the baud in the TX_BYTE subroutine.

    what is the difference between using OSCXT2 and OSCHS2. I used the first one at 50 MHz in assembly and it was Ok. why it is not working with basic.
