can you read the 89C2051 with another programmer or is it damaged?
if you explain what programmer it is or where you got it maybe someone has the software for it?

Can you post a schematic of the programmer?

This is by far the best and easiest & most reliable programmer for the at89C2051.

follow the schematic carefully and you will have a good programmer.
If your PC does not have a serial port, you can use a good USBtoRS232 cable (not a cheap knock-off from China!).
