 The Java Fiscal Device API is a medium-level API to communicate with fiscal devices such as fiscal printers. It handles the communication protocol and the formatting and parsing of the protocol packets, and provides event-based notification for certain events such as out-of-paper events. It was made for Hasar printers but also works fine with Epsons, after some small protocol differences were accommodated.

 Update
 ------
 
-This software depends on an implementation of its own `FiscalPort` interface to communicate with devices. It includes a `SerialFiscalPort` implementation for serial ports that is a thin wrapper over Sun's Java Communications API (`javax.comm`). Unfortunately Sun has deprecated this API without providing an alternative and some operating systems are no longer supported. However there are some free and commercial implementations of `javax.comm`, for example [RXTX](http://rxtx.qbang.org/). There are also other serial port drivers over which a `FiscalPort` could be more or less trivially implemented; see [java-simple-serial-connector](https://code.google.com/p/java-simple-serial-connector/) and [serial-comm](https://code.google.com/p/serial-comm/).

-Please contribute your drivers to the project. They will be accepted if they are tested to work and implement `FiscalPort` and `FiscalPortSource` classes in their own package, in the style of package `com.taliter.fiscal.port.serial`. (Modifications to the current driver will not be accepted unless they are bug fixes.)
+This is why I have added `RXTXFiscalPort` with support for two alternative serial port drivers, [RXTX](http://rxtx.qbang.org/) and [nrjavaserial](https://github.com/NeuronRobotics/nrjavaserial). RXTX is known to have [issues](http://stackoverflow.com/questions/12317576/stable-alternative-to-rxtx), especially the old 'stable' release, so nrjavaserial might be a better bet. There are also other serial port drivers over which a `FiscalPort` could be more or less trivially implemented; see [java-simple-serial-connector (jSSC)](https://code.google.com/p/java-simple-serial-connector/) and [jSerialComm](http://fazecast.github.io/jSerialComm/).
 
-I no longer have access to fiscal devices and thus I cannot test. For this reason I cannot implement `FiscalPort`s that wrap these new serial port drivers. However this API is still being maintained: no bugfix releases were made in 10 years because, although it has many users, no bugs were ever reported against it. Debugging would be harder now without test devices but I will still try my best to fix the code if a bug is reported.
