Missing Functionality for real use cases

[rajtan]

Thanks for the good / efficient code for the R305 library.

I think this is a library with partial functionality with efficient code. For example, uploading / downloading templates from the host system is missing. As per the documentation, there is a restriction on packet length in certain commands/operations. The templates and character files are longer than limit and need to split into multiple packets. "EOP" (end of data packet) identifier has been used the in the package identifiers list in R305.py but not used. This will be required for actual usage.

Further, I am skeptical about the code in DownChar function. As per the documentation, it will only need 1 parameter of BufferId. You have made provision for PageIds as well. The examples sited have not used the DownChar function. Correct me, if this is not the case and there is some code which I have missed in DownChar. Has it been tested?
