Modebus Communication Improve for an Embedded Software

we have an specially designed embedded computer which is communicating with a standard industrial modebus flow meter [login to view URL] layer is already solved at basic levels. Currently we are able to read some values but we would like to improve firmware of our computer to add new features according to Modebus protocol document. Main software is written in C with Keil Compiler for 80C51 8-bit micro controller family with extended memory 96 kB Flash with 2 kB RAM of NXP. Due security reasons we will give certain parts of main program and want freelancer to create or improve codes. Please also note that :

- bidders need to sign NDA.

- bidders should accept to use C not other language like C#, Basic, Assembler etc.

- bidders should have experience in embedded devices firmware programming.
