 		 #182378 - USB dongle
Responding to: ???'s previous message
As Andy notes, it takes skill and time to use an unknown processor.

For low count of units, it is way better to use one of the USB dongles, where the 8051 think it talks directly over a UART link while the PC sees a USB-connected serial port. So the time already invested into gettin an UART to work can still be used. It's just that the MAX232 chip (or whatever was selected) has been replaced with a slighly more advanced module that not just changes voltage levels of the signals but totally repackages the data into USB data frames.
