I don't have Kermit capability on my 41 (not directly at least; maybe it could be done) but I do have the FSI164A HPIL-to-RS232 interface converter which is nearly identical to the HP82164A except that the FSI came with two RS-232 channels standard, and optionally up to eight, and optionally battery-powered. I suppose a module could be written to do the Kermit protocol over serial with the __164A. If you have HPIL, you can interface to nearly anything, one way or another. I also have the HP82165A HPIL-to-parallel interface converter, the HP82169A HPIL-to-IEEE488, and the HP92198 HPIL-to-80-column video. My HPIL module has the Extended I/O module built in, so it's a double module.

I'm only seeing the USB stick. USB is much, much more complicated than SD card. To further simplify things, SD card has an SPI mode.

then you're not looking right: go to minute 3:40, it even says on the screen message " Use a micro SD Card for data transfers"

Ok, my mistake. I took the first post too literally and went to 3:50, but missed the seconds between 3:40 and 3:50 where it shows him inserting the microSD card.
