I have a serial application that uses the serial port for communications to hardware that I have developed. The application works fine with a m515. However the application does not work with the Tungsten. The application software adheres to OS 5.0. I have monitored the serial transmitter line and have found that there is a 312 kHz oscillation riding on it. Although the Tungsten hotsyncs just fine via the serial port on a PC, the serial transmitter will not work with my hardware. The hotsync connection to the PC results in a 30 volt peak-to-peak swing with the oscillation swing of 10 volts peak-to-peak that allows the PC serial receiver to properly test incoming bit levels. My hardware only allows 20 volts peak-to-peak swings. Which is not enough to allow my hardware receiver to properly test bit levels. Result is that my hardware can not read data transmitted from the Tungsten serial port. Regardless, the oscillations should not be seen. It appears that! The oscillation is 32 times the bit rate frequency of the transmitter. Palm has told me that if the Tungsten hotsyncs ok serial with my PC then there must be a problem with my software or hardware. Do I have a broken Palm?
