    Default rs232

    hi ive connected a gps unit up direct to my serial port via a max232 chip

    but i'm only seeing the nmea string when i toggle the power on and off to the rs232 chip, anyone have any idea why this is

    i'm using the attached schematic

    i did have the unit connected to a pic micro waiting for a particular nmea string so i could parse it but the pic wasn't seeing anything, so thought i would connect it directly to the serial port just to see if its outputting anything
