I am trying to send 8-bit data through Null Modem using THR and RBR registers. Have set baud rate 9600. But unable to receive data on reader side. Is there any more register settings are required.?
You have to first reset the 7th bit of LCR to 0, and then set how much bits you want to sent from writer/receive in receiver. then outb charcter in THR, n inb from RBR at receiver side
Actually, I had done same as it should be. Finally found that there was hardware issue and serial port was not working. Finally, on another system it worked successfully...
