Billy,

Please tell us more about your requirements so we can point you in the right direction or donate code.

For example, on the 8051 side, what language/toolchain would you find acceptable? Are you looking to just send simple ASCII text (i.e., strings) or do you need some kind of packet protocol with binary transparency and CRCs?

On the PC side, again what language/toolchain would you find acceptable? For what operating system etc.?

Please elaborate.
