[BRLTTY] 3.10-4 not as demurely in the background as it should be

[Lee Maschmeyer]

Hi folks,



I'm not sure whether we're supposed to switch to 3.10-x or if that's a 
special debug version. I'll switch if that's advisable.



3.10-4 is running in a command prompt. I did not exit the prompt window and 
things seem to be OK in other Windows so far.



Besides the command prompt I also have Cygwin active using the same instance 
of brltty. Cygwin is set to put Jaws braille to sleep when it gains control 
and, somewhat less reliably, let Jaws braille wake up when a non-console app 
gets control.



With 3.10-4 whenever Jaws braille wakes up, brltty spits out 3 identical 
error messages in Cygwin. The first is wherever the cursor happens to be 
(such as on the line with $PS1) and the other two are on the lines 
immediately below it. The message is:



brltty.exe: cannot open serial device: com1: Resource temporarily 
unavailable



I'm not sure the same error appears in the command prompt, even though it's 
the window that started brltty. I made a mistake and switched to that window 
when Jaws was still running and got loads of those messages, but Jaws 
braille is not set to go to sleep in the command prompt so that's not 
surprising. I tried terminating Jaws, going to and from the command prompt, 
and starting Jaws again, and did not get the error that time. Whether that 
can be relied on I don't know.



HTH,
