Hi Geert, > Which port are you using?

Upon calling open() on the tty device sci_set_termios() and sci_set_mctrl() are called in this order. When issuing changes (baud rate, CRTSCTS...) only sci_set_termios() gets called. On calling close() sci_set_mctrl() and sci_shutdown() are called in this order. > Have you tried using GPIO RTS/CTS instead of hardware-assisted > RTS/CTS? > Does it show the same behavior? > When adding support for hardware-assisted RTS/CTS, I used the > behavior of GPIO RTS/CTS as the expected behavior. No, I haven't tried GPIO RTS/CTS so far. How would this be configured? Regards, Christoph ��.n��������+%������w��{.n�����{��ǫ����{ay�ʇڙ���f���h������_�(�階�ݢj"��������G����?���&��
