rs485.c, is not meant to be compiled. The 'example', is ex_rs485.c (in the examples directory, not the drivers directory), which then loads this part as an include file (why CCS used .c as an extension, rather than .h for this file, I do not know). rs485.c, needs the extra definitions in the example file, before it'll compiler.

That is ex_rs485.c, which is included with the compiler, not 'ex_rs485chat.c', or 'rs485.c'. The version that comes with the compiler, will compile OK. The latter version (which is what you get if you download it seperately), will give problems depending on your compiler version, unless you use a chip with more ROM (16F648A).
