Help ~!!! About the Android U3D development of the serial port-CodePudding

I just want to read an android to a serial port data, but the android has been submitted to the DLLNotFindExcetion: MonoPosixHelper
How to deal with, just want to read a serial port...
Hardware must be no problem, use Google's open source API serial port tried, online search for a long time still no results, only to ask everyone, help...
Below is the code:

 void SerialPortInit (string com) 
{
String portName; 
If (com==null) 
PortName="COM0"; 
The else 
PortName=com; 
Int baudRate=115200; 
Parity Parity=Parity. None; 
Int dataBits=8; 
StopBits StopBits=StopBits. One; 
Int ReadTimeOut=400; 
SerialPort sp=null; 
Sp=new SerialPort (portName baudRate, parity, dataBits, stopBits); 
Sp. ReadTimeout=ReadTimeout; 
Try 
{
If (sp. IsOpen) 
{
Sp. The Close (); 
Sp. The Open (); 
} 
The else 
{
Sp. The Open (); 
} 
} 
The catch (Exception ex) 
{
The Debug Log (" error: "+ ex. Message); 
} 
}
