Method Detail

getInstance

public static DallasLock getInstance()

getPort

public gnu.io.SerialPort getPort()

Specified by:

getPort in interface TagReader

getId

public String getId()

Specified by:

getId in interface TagReader

serialEvent

public void serialEvent(gnu.io.SerialPortEvent evt)

Listen to the serial port and collect incoming data in a buffer. How the buffer is handled depends on the protocol. (A) Dallas lock with ASSI protocol in 'Standard Mode' (not polling): A lock message consists of either 21 bytes (serial number) or 5 bytes (out message) We evaluate the buffer when LF is recognized. If the buffer does not contain enough characters we reset the serial connection. Removing the token is recognized by "OUT" (B) Promag PCR300: We evaluate the buffer when LF is recognized. Removing the token is recognized by ESC.
