It works on macos but not on linux, ie, I have a usb-serial dongle connected to a serial device (a CAMAC controller), and I do an os.open() with 'wb+', followed by a io.fdopen(). I can talk to my device on macos BigSur 11.2, buffered, but not on Linux which throws the non-seekable error when I do the io.fdopen(). ---------- nosy: +ken.teh _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue20074> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
