Code Sample 13 shows the implementation of CommConnection:
Sample of a CommConnection accessing a simple loopback program
CommConnection cc = (CommConnection)
Connector.open("comm:com0;baudrate=19200");
int baudrate = cc.getBaudRate();
InputStream is = cc.openInputStream();
OutputStream os = cc.openOutputStream();
int ch = 0;
while(ch != 'Z') {
os.write(ch);
ch = is.read();
ch++;
}
is.close();
os.close();
cc.close();
Sample of a CommConnection discovering available comm Ports
String port1;
String ports = System.getProperty("microedition.commports");
int comma = ports.indexOf(',');
if (comma > 0) {
// Parse the first port from the available ports list.
port1 = ports.substring(0, comma);
} else {
// Only one serial port available.
port1 =ports;
}
