Follow-up Comment #2, bug #53774 (project octave):
ok running on my computer under gdb, when running instrument-control with the
following:
more off
a = serial('/dev/ttyS0', 9600, 1)
while (1)
[x,c] = srl_read(a, 1000)
end
When running in octave 4.2.1, it does not create new threads.
In octave 4.9.92, running the same code, gdb is showing a new thread created
each time srl_read is called.
The current serial code sets a a signal handler before calling the os read of
the serial port, and then restores it, so updates on octaves set signal
handler must be doing something.
