If by "serial comm" you mean the RTX en TXD pins of port 3 and SFR "SBUF" of your µC : you can't for several reasons.
If you have further specific questions I'm willing to answer them... ...
I have working code for 8051 system documented partially in English and Dutch but I will not give it away so easily, you have to prove me you working on it, not just asking for working code and expect it to fall into your hands. What's the point getting it just like that with no effort?
Please allow me te repeat myself "If you have further specific questions I'm willing to answer them... ..." in other words, show me what you already did, tell me your technical, coding, ... ... problems and I will answer them as good as I can.
What do you think about the mode 2 and mode 3 thing?
Is any mode all right for you or not?
I assign personal codes to specific non-printable keys, is that ok for you?
How will you implement the code, interrupt based or not?
How will you handle the "Pause" key in normal mode (7 bytes for one key
)?
PS: That other code is in Polish, you know from Poland somewhere in Eastern Europe... ... I didn't understand the language either but I managed to understand some parts of what he's doing
