    Talking max232 vs direct serial

    Hi,

    I used a pic to talk directly to hypeterminal using debug and series resistors.

    I thought I was doing the right thing by inserting a max232.

    Now my code dont work!

    I noticed in the the max inverts the data in as well as out.

    Does the pic now get fussy, or do I need to use a different comms command?

    I am using the max to achieve greater range, and eusudo multidrop.

    Check your command.
    You're probably using inverted RS232.

    Yep, You were correct!

    I checked the code and all I had to do was select True mode in Debug.

    Thks for the response.
