Hi all, I have written a program in VC++ to write a char array of 13 bytes on COM port using 9600-N-8-1 parameters. when i send this to my target device it responds, but same program when i send through 89S51 my device does not respond.To set 9600-N-8-1 i have written 0xFD value. Can anyone no the reason for such strange behaviour. Please let me know.... rutu.
