Create Palm Software to Communicate with Your Serial Devices!

Are you wondering how to write software that will allow you to communicate to serial devices with your Palm? Just download PalmTerm software from the B&B Electronics website for a complete and easy example to get started.

PalmTerm simply displays the characters transmitted and received. You can define up to 5 transmit strings which you can include regular text or hexadecimal characters that are specified between <>.

PalmTerm is a simple freeware program that demonstrates serial communications with the Palm OS. It was created with CodeWarrior. PalmTerm comes with source code and includes all the serial routines that you may need to start writing your own serial communication programs.

Simply cut and paste the following serial communications routines and with minor modifications, get working in your application.

void OpenSerialPort(void)
void CloseSerialPort(void)
void TransmitData(char* chrBuffer)
void ReceiveData(void)
