[jerkymotion]

hi every body
I am using mplab...I am not expert in microcontroller programming ...
I have made GUI to send data to my serial port ...
now I want to write a program in PIC that executes accordingly the serially sent data to my serial port and send data back to the serial port as well....
I am beginner to this so please help to begin with serial port communication..

Some compilers have examples very easy and 'ready-to-use'.
Are you performing that on C or ASM language ?

Receive a string from the HyperTerminal

char *Receive_MSG(char *String, unsigned short int MSG_Length)
{						
	unsigned short int Index = 0;	// Message Index
	
	while(Index < MSG_Length)
	{	
		String[Index] = Receive_Byte();
		if(String[Index] != 13 && String[Index] != 10)
		{
			String[Index + 1] = '\0';		// Set the next character to NULL
			Index++;
		}
		else
		{
			String[Index + 1] = '\0';		// Set the next character to NULL
			break;
		}
	}
	return String;
}

Send a string to the HyperTerminal

void Send_MSG(char *Message)
{
	unsigned short int Index = 0;
	while(Message[Index] != '\0')
	{
		Send_Byte(Message[Index]);
		Index++;
	}
	Send_Byte(13);	// Send CR
	Send_Byte(10);	// Send LF
}
