No. I mean to check $PATH just before you start brltty. At that same point, you 
might also verify that screen is in $PATH another way:

   type screen

The type command should display the path to the screen command that's being 
found. That might be worth verifying in case you have more than one screen and 
the wrong one is being invoked.

>I can tell you that /usr/local/bin is in the path normally. 

Here's another thing to try, and this can be done after brltty has been 
started. Nevertheless, please do it from the same session. Right after starting 
brltty would be best. Execute this command:

   screen -p 1 -X stuff a

That should input the letter a, which, in turn, should be echoed. Does that 
work or do you get an error message?

>Meanwhile here is the log with the added item.

It shows that the screen driver is doing exactly the right thing, but still no 
error message from screen showing why it's failing.
