Yes, Russell, I thought of that. I first need to install the driver for the usb-serial device, recall how I did that on the laptop, and try to do it the same way. But I will pursue that when I get access to the desktop.
Is there a line on the usb that should be bouncing up and down when RXD is bouncing? BTW, I notice that the designations rx/tx seem to switch depending on which instrument the terms are referred to. The schematic I have clearly shows that the designation RXD applies to the data line out of the dmm. TXD is the line sending stuff into the dmm. I am assuming that this is OK since I clearly see 10 groups of pulses out of the dmm when I send the command --samples 10.
