Does this occur all the time or transient? does write term all complete
with disconnect of the terminal session?

The device poll fails *every time*, and every time I have run things
manualls I got the same error as above.

It looks like the error happens when the switch is sent "exit\r" and
drops the session. All the commands complete.

Interesting, this is the end of write term all, and the start of write
term from the .raw file

Notice the lost echoback, we see the prompt, but not where "write term"
is entered.

At least, the
