Hello Sukandar,
file is busy (errno 16) is the generic error that the tty returns if
there is a problem in open, it does not really mean "busy". However I
am interested on why you fail to open a connection.
Hi Marco, thanks for the reply and your interest.
So, first of all, how long is the time between you starting the open
and getting the error back ?
30 seconds
And when you attempt the connection, do you see the connection
starting (look at the menu extra icon on the top right of the screen,
does it change into a bluetooth B with the three dots acrioss ?).
yes, it does
also, it stays that way for another 30 seconds after the error message
And last: is the "LinTech RS232 industrial adapter" something anybody
(me) can buy (so I can repro the problem) ?
yes:

Hi,
I'm trying to open a Bluetooth serial device but get an error message
that the file is busy (errno 16).
The box I'm trying to talk to is the 'LinTech RS232 industrial
adapter' (http://www.lintech.de/english/index.html). Doing this from
a Win2000 terminal works fine.
The device is created with the Bluetooth Serial Utility as
/dev/cu.linout (resp. /dev/tty.linout) and shows up OK (e.g. in ZTerm
or when talking to the IORegistry). However trying to open it gives
me the above error message, no matter wether I try in ZTerm, Tcl/Tk
or C (and I'm not aware of any application that might claim the
device exclusively).
System is OS X 10.2.5
any ideas?
Thanks,
Sukandar
