My goodness. How does one make sense of the debug information? In less
than two minutes, I generated over 19000 lines. I actually was able to
capture a Finish command that responded quickly, plus a second that
responded slowly, so in theory the information we need is there, but I
don't know how to ferret out what's going on.
Physical setup: Kermit 95 is on one PC, the PDP-11 emulator is on
another. They're connected by a null modem running between the COM
ports. It should be noted that the Kermit 95 machine is using a USB to
COM adapter.
