[PLUG] com port in guest to usb in host (virtual box)

I agree completely.  I have downloaded sigrok-cli.  Now I have to try to
understand how to use it.  (I feel a bit overwhelmed.)
Where do I put the driver? Is output/input with respect to the external
device or the software?  I assume the device, judging by the longer list of
output formats.  What is the protocol?  Do  I need to know, or will the
driver decide?

sigrok-cli -V
sigrok-cli 0.5.0

Using libsigrok 0.3.0 (lib version 2:0:0).
