NO?? what about now
SEROUT PORTC.6,4,["HELLO"]

Since this PIC have an internal USART, why you don't use it??? HSEROUT, HSERIN + an external inverter circuit like MAX232.
ya..i got include the INCLUDE "MODEDEFS.BAS" and define osc X..in my code. I haven try PIC 16F84A, but i think should be nope problem with the code that i mention above...thats y i am thinking is it PIC 16F874A problem? by using simple serin and serout command...

By the way, i got include external inverter circuit like MAX232 in my hardware...emmm, just panic now, but i am sure my connection is correct...just receive the weird character only...

emm..hehe, can u send me the simple code with HSERIN and HSEROUT to test...hopefully, can settle soon...
