hi all,

i have few doubts-

1) i have an old disfunctional programmer for 89C51 which works through computer serial port, i have found that the RESET pin in the programmer is always kept high. is this the problem?

2) want to know how one can make out if the microcontroller is running? because i dont know how to make out if it is software problem or hardware problem.

please help me.
