Package com.thecoderscorner.menu.remote.rs232

Class Rs232RemoteConnector

java.lang.Object

com.thecoderscorner.menu.remote.StreamRemoteConnector

com.thecoderscorner.menu.remote.rs232.Rs232RemoteConnector

All Implemented Interfaces:

RemoteConnector

public class Rs232RemoteConnector
extends StreamRemoteConnector

This is the R232 connector that can talk to a tcMenu library application running on an embedded Arduino. Normally one uses the Rs232ControllerBuilder to construct the whole remote stack instead of creating this directly.

Modifier and Type	Method	Description
protected void	getAtLeastBytes(ByteBuffer inputBuffer, int len)	Reads at least the number of bytes requested waiting if need be for more data.
String	getConnectionName()	Gets the name of this connector locally
protected void	sendInternal(ByteBuffer outputBuffer)	performs a send of all bytes in the output buffer until the output buffer is empty
void	start()	Starts the communication channel, so it will attempt to connect with the configured device
