Alexander, >I just don't know how to do this. What type of communication should I >choose?
That depends on your connection. If you have a serial port cradle (or modem), you'd want to use a serial connection. With a USB port cradle, you'd want to use a USB connection. With a network cradle (or wireless net), you'd want to use TCP/IP. If you have to support multiple methods, you have more work cut out for you... >You are talking about opening a USB port as a serial port and >awaiting instructions. How do I open USB port as serial port from palm app The same as a serial port -- see the Serial Manager docs. From the palm side, only the port number would be different and you can even use a port constant which has the Serial Manager automatically detect whether a cradle is USB or RS-232. (See port serPortCradlePort, 0x8000 in Serial Manager docs.) >and how to I connect to it from desktop PC app? What's the port name? The desktop side would be much easier with a normal serial port instead of USB. AFAIK, using USB from the desktop side will require a manufacturer specific device driver. For example, I believe Handspring's and Palm's USB drivers are incompatible with each other. I don't know how you'd do a USB connection from the desktop side. For a regular serial port, you'd treat it just like any serial device.
