I want to make two AT89c51 mcus to communicate serially
one mcu will transmit whatever data is on its port 1 serially to another mcu that second mcu will show this data on its port 1.
I have written code but its not workingplz check the following code and tell me if there is any problem and if code is correct what may be other possibilites that i m not getting desired output on port 1 of receiving mcu:

//----- Transmit Prg
#inlcude <reg51.h>
void Serial_Init(void)
{
SCON=0x52;
EA=1;
ES=1;
TMOD=0x20;
TH1=0xE6;
TR1=1;
}

void Transmit_Char(unsigned char c)
{
SBUF=c;
while(!TI){} //Waits until transmit
TI=0;
}

void main(void)
{
unsigned char tchar;
P1=0x00;
P3=0x00;
tchar=P1;
Serial_Init();
Transmit_Char(tchar); // Here Sends port P1 to serial port
while(1){}
}
// End of Prog




/-------- Receive Prog
#inlcude <reg51.h>
void Serial_Init(void)
{
SCON=0x52;
EA=1;
ES=1;
TMOD=0x20;
TH1=0xE6;
TR1=1;
}

void call() interrupt 4
{
if(RI)
{
P1=SBUF;
RI=0;
}
}

void main(void)
{
Serial_Init();
while(1){}
}

// End of Prog
