 		 #168047 - Which 80c5/52 mfg and series are you programming
Responding to: ???'s previous message
Please advise as often the DTR/RTS serial lines are used in the serial port timing to put the 80c51/52 in to programming mode.

The DTR/RTS signal lines on a USB to serial port many not be instep with the Tx and Rx data.

So be aware of this fact.
