I tried to start a communication between 89C2051 and 89C52 via serial port, but I could not. My assembly routins are working properly, but when I wrote the C code ...!!! Any suggestion or comment??
There are 'C' serial comms examples in the downloads section, and Mark Odell has posted his free driver here (use 'Search') Have you tried running one end of your link in the simulator, or just talking to a dumb terminal?
