Hallo@all

I need help to connect my 16F877 PIC with the Resistors/Serial Port.
I does not work with the 5 Volt Power Supply.

what i have for 16F877 is :

TXD (3) ------[4.7k]-------VPP/MCLR

GND (5) -----------------VSS (GND)

DTR (4) -------[4.7k]----RB7/PGD (DATA ???)

CTS (8) -----------------RB3/PGM (DATA ???)

RTS (7) -------[4.7k]----RB6/PGC/CLK

are the Connetions wrong ? I dont know ?
IC Prog tells me the Error Code on 0000h.



What stands the two data lines for ?!
DTR (4) -------[4.7k]------DATA (????)
CTS (8) ------------------DATA (????)
