Hi Qaisar,
I tried your code on Proteus:
1. by connecting 8051 TXD directly to virtual terminal RXD as shown in the figure- I got garbage data on the virtual terminal.
2. by connecting MAX232 and RS232 between 8051 and virtual terminal- no data was recieved on the virtual terminal.
Another doubt I have is, shouldn’t we enter the ASCII values in hex instead of decimal?
Aniket.
