I use the serial port quite often on devices from OS 2.0 up through 5.0 including the Clie. Few problems to speak of. Got other details that might help narrow down the issues?

Devices with the 'universal' connector have a pin used by the device to detect insertion of cables, cradles and peripherals. The beep is the OS detecting the insertion. Hasn't affected our ability to communicate except when the resistors used to set this port are wrong. ----- Original Message ----- From: "Mike" <[EMAIL PROTECTED]> Newsgroups: palm-dev-forum To: "Palm Developer Forum" <[EMAIL PROTECTED]> Sent: Wednesday, October 29, 2003 3:31 PM Subject: Re: Serial port frustration > Let me add that there are no errors reported when I open the com port. > > -Mike > > > "Mike" <[EMAIL PROTECTED]> wrote in message > news:[EMAIL PROTECTED] > > I don't understand why this has to be so hard. > > My program uses the serial port.
