Hi I have implemented the stuff // and set the port6<7> pin LOW. Now the upper PNP transistor isn't conducting anymore. Now TX and RX works Here are the program #include <lnp.h> #include <conio.h> #include <string.h> #include <lnp-logical.h> (...) (16 years ago, 20-May-08, to lugnet.robotics.rcx.legos)
