I need a little nudge in the right direction here; I'm designing some hardware that interfaces to the Palm via the serial connector, but all I really need to do is sense a contact closure. I can design my device to assert the hardware handshake lines, but I don't know how to programmatically check the status of the CTS/RTS lines. Or maybe should I use the GPI0 or GPI1 interrupt lines? I've searched the SDK for relevant info, but can't find any. What's the best approach?
