I've been trying to establish link between 89c51 microcontroller kit (Made by : SPJ Systems, India) and my PC.
I wrote a small routine which waits for a byte from serial port and throws it back after incrementing the recieved byte by 1. I had tested this code with the simulator provided by the manufacturer. Also I had tested it with the COMTEST utility available with Programmersheaven.com, after porting my code onto the kit. It works fine.
Now the problem is that my program running on my PC (AMD K6 with MS DOS , code developed using Turbo C, BIOSCOM library used)is unable communicate with the kit. Despite trying several combinations of baud rates, I am recieving timeout error while sending (I am able to recieve from the kit).
Pls. Help me. Thank you.
