I understand. Some of the compilers offer extra functionality beyond the C standard library. HI-TECH comes with various examples and samples, as well as some extra functions (e.g. EEPROM read and write). Not sure what it has for I2C and RS232 -- I usually roll my own, sometiumes using their samples as a guide. Regards, -- ______________________________________ Andrew E.
