Modbus library with 4-byte types support

Hello.

I'm using jpmzometa's modbus library with xbee and Mango M2M. It works very well but it has a problem. The library only supports 2-byte types. Does anyone know a modbus library for arduino with 4-byte tipes support?

Thanks.

I believe 4 byte is non-standard. You may have to rewrite the library to implement that.

Yes. You're right. I'm thinking that the fastest and easiest way is to convert float numbers to a equivalent integer.

Thank you.
