#141010 - i am having serious problem with serial |
i am having serious problem using serial port
i have more than one code all working very good on the simulator (i mean that the charcters to be sent out are transefered to sbuf in order )but i got no output from the txd and i have two hw circuits to connect the max 232 i tried both of them and also i have my sw terminal on the pc which is working very good sending and recieving to/from other pc (very simple c# code if any one need it) by the way paud rate , stop bits ,etc all the same on both the assembly and the c# codes so if any one can guess what is the problem I will be very thankfull |
