Palm uses the IrDA protocols IrLAP, IrLMP, TinyTP, IrCOMM, and IrOBEX. See
http://www.irda.org for info on these protocols if you're interested.
- On the device, you can use the IR Library to communicate using the first three
protocols.This is fairly tricky. These protocols let you send packets back and forth.
- You can use the serial manager to communicate using IrCOMM. This protocol gives you
a fake serial port on which you can send bytes back and forth. This was added as an
extension but is now part of the OS. This is what IR HotSync uses.
- And finally, you can use the Exchange Manager to communicate using IrOBEX. This
protocol lets you send or receive a single object, including meta-information such as
filename and MIME type. You can have your app register to receive data with a specific
extension. If you have your PC app use a filename with this extension, it should work.
I haven't used it, but people mention QuickBeam. This is how the PIM apps beam data.
I put these in reverse order. Use the last if it suits your purposes. Use the first if
all else fails!
HTH.
