Modbus Slave Implimentation

Can anyone suggest a good Modbus RTU Slave / Master library that will work fairly easily over the onboard UARTs? I am, using a MEGA2560.

The ArduinoModbus library looks to want a particular shield, and utilises the RS485 Library. I am hoping to operate over an RS232 Link with Half duplex. (as I have a nice isolated 485 to 232 converter for the industrial environment it will be operating in).

I note there are a lot of libraries on Git hub that look like they will do the job. Any recommendations?

I'm using a slightly modified version of this library for my project. It works well with hardware serial interfaces (on AVR). If you're interested, this is my working branch.
